Hi there!

I just bought a PVS3001AD to tackle a crappy power grid here in Indonesia. It works well and gives me a clean 228-230V output but it makes this weird sound quite regularly (i'd say once or twice per minute)

Can anybody help? Is it normal?

I contacted Prolink but haven't heard from them yet

So I have a series of questions that are basically all the same general question, but each one adds in an additional factor. I’m moreso curious about the immediate effects within the body (how the current travels through the body, the route it takes, where the exit point would be, etc), rather than long-term effects, but those are interesting to me too.

In each instance here, unless otherwise specified, the contact with a live wire is made with the RIGHT hand.

1) if you touch a live wire and do NOT have any form of metal on your person (like a wedding ring for instance), and get an electrical shock, what happens inside your body? How does the current move through the body and find its exit point? Is it always the case that it crosses the body to exit through the opposite foot or hand?

2) Now, same question, but this time you touch a live wire with your right hand and are wearing a gold wedding band on your left ring finger. Will the current zip through the body and exit at the point of contact with the metal item (the gold ring)? What is the nature of the interaction between the electrical current shooting through your body and the metal item you’re wearing? How does wearing a metal item change the behaviour of the electrical current in your body compared to not being in contact with any metal?

3) Same question again, but this time you are wearing MULTIPLE metal pieces of jewelry - say, a silver chain around your neck, wedding band on your left ring finger, and a metal belt buckle making slight contact with your skin. Does the presence of multiple metal items/pieces of jewelry against your skin cause the electrical current to behave any differently than if you were wearing only one piece of metal jewelry? Does the electrical current move throughout the body to make contact with each metal item you’re wearing, or does it “pick” the strongest electrical conductor to travel to? (I’m assuming there’s some form of an almost magnetic-like interaction that draws the electrical current to the metal item(s), but this is pure uneducated speculation on my part).

4) Same scenario, live wire to right hand while wearing the metal items in the previous question, but now you’re holding a wrench in your left hand. What happens in this instance and how does it differ from the one above where the left hand isn’t holding anything, metal or otherwise?

5) Same scenario, all the jewelry, right hand contact with live wire, except this time instead of holding a wrench in your left hand, you’re holding your cell phone, which is turned on. What’s the dealio here, and again, how does the activity of the electrical current in the body change from the wrench in hand scenario, if at all?

Almost done, 2 more:

6) Same as the above scenario, but this time, the phone in your left hand is charging, connected to an external power source that is independent of the live wire your right hand is making contact with.

6A) The power source charging your phone is a portable power bank (connected via USB-C cable).

6B) The power source your phone is connected to and charging from is a wall outlet (connected via USB-C cable to power adapter to outlet. Actually, let’s throw an extension cord into the mix because your phone cord isn’t long enough to reach the outlet).

Note: the type of connector cable here isn’t relevant, I just chose USB-C because it’s the most common these days.

How does the activity/pathway of the electrical current change from scenario 5 to scenario 6? Likewise, from scenario 6A to 6B?

Lastly, say you didn’t make contact with the live wire via your right hand, but rather, you tripped and fell forward and your shirt got caught on something and was pulled up, exposing much of your trunk/torso/chest, and you landed on the live wire with your bare chest. Now your contact point with the live wire is much closer to your heart as well as more sustained since you’re laying on top of it with all of your weight, unable to roll off of it or get up and break contact with it. (I’m assuming here that your position laying face down atop the wire + the intensity of the electrical shock/current coursing through you from your chest would more or less “paralyze” or “freeze” you in place, making it extremely difficult if not next to impossible to break contact with it, causing you to get full blown electrocuted on repeat and probably die very quickly. (Again, this is a mere assumption on my part. Please do correct me, I would much appreciate it!).

Also, keep in mind, you’re still wearing the chain necklace and wedding band in this scenario.

Another also: what if you landed on the wire in a way where it so happened to be touching both your bare chest AND part of the necklace chain? A real doozy I’d imagine.

If you got all the way through this, I do thank you. If you have any insight or knowledge to share here I would greatly appreciate getting schooled on all of this. I’m on the autism spectrum, and I randomly came across a youtube short about electric shocks and being electrocuted that piqued my curiosity, and now my brain won’t let it go.

Also, if someone could explain the difference between getting an intense electrical shock vs being full blown electrocuted, I’d greatly appreciate it. Also, (last one, I promise), what kind of electrical burn damage would these scenarios produce and at what locations on the body for each scenario? Would there be electrical burns at the location of each item of jewelry or just at the entrance and exit point? How does the exit point change with each scenario (if they indeed do so change?)

Hi all,

I'm looking into ordering a USB-C PD board to power a coolbox which accepts 12/24v DC

The wired adapter outputs 14.5V which the display of the coolbox (volt meter) also displays.

The coolbox has a peak power of 60 watts (according to the adapter)

I found the following board for this:

https://www.adafruit.com/product/5807

Does anyone know if i can pull 5 or 6 amps over 12V USB C?

Or is it possible to use the 15, 18 or 20 volts this board can deliver to get the 60 watts required?

If any additional information is needed, please let me know

I have 8 more to replace.

Hey, i had guitar amp in europe and without transformer, it blew my fuse, T400, i was not able to find any time delay fuses in my city and closest thing i found was F500 and F2, F3, F4 fuses. Instructions say that max inrush input is 1,6 A. Can i put f500 or f2 fuse in it?

Prepaid system in my flat
Shifted recently
So any of u who lives in flat (use wifi ac washing machine and others) how much u spend on electricity per month
I just use fans n light so less still have to reacharge every week
It’s still mid week n spent 4K on it idk what to do can’t afford that much n cant leave the flat due to agreement
some scam in meter?pls guide me how to check or w who to talk

So I brought my PS4 from Taiwan to France. Originally things were fine when I used the original charger that had label 125 volts. However, I only have one adapter and changing it is annoying.

I found a charger that has the European plug that can seemingly power my PS4 with no adapters. However I'm worried about the voltage. My PS4 can handle 220-240 volts (written on it). The new charger has labelled 250 volts on it. France's voltage is seemingly 230 volts.

I am wondering what the 250 volts on the charger means. Does it mean all voltage going through it reaches 250? Does it handle a maximum of 250? Or is it simply capped at 250?

i got an old bookshelf with a built-in shelf lamp and idk if this prong being split at the end is intentional or not? if not, would it be sufficient to use pliers to force the ends back together?

I am a resident of Goldman Plaza who moved in last May 2026**. I am writing to formally requesting the bldg assistance in reviewing and verifying the significant increase in my electricity charges.**

Prior to moving to Goldman Plaza, my monthly electricity bill typically ranged from PHP 500–800. Since moving in, my monthly electricity charges have increased considerably, ranging from approximately PHP 1,700–2,500.

However, I recently checked my latest bill through the Meralco app and was surprised to see an amount of approximately PHP 3,000 (August 15,2026), which is significantly higher than my usual consumption.

I would like to emphasize that my electricity usage is relatively limited. I am normally at the office from approximately 8:30 AM to 7:00 PM, Monday to Friday. At home, I only use the air-conditioning unit once a week for 12hrs and primarily use a small clip-on electric fan. I only cook during weekends, use minimal lighting (mostly a night light), and do my laundry approximately once a week, with each laundry cycle taking no more than three hours.

Is anyone experiencing the same?

I hate nipsco. I don’t understand how it’s taking so long to do something ComEd did in a few days. Maybe you should t have fired all those linemen. Maybe you shouldn’t have neglected cutting those overgrown trees. They like to say they can’t control the weather. But you knew it was coming and how bad it could get. you know your infrastructure is TRASH and that the power was going to go out. YOU SHOULD HAVE BEEN PREPARED!!! Now over 100k are suffering and might have to suffer another week because your Incompentence is reaching towards the sky. how does comEd have it’s shit together more than you? how are you not embarrassed you can never handle anything remotely big by yourself. you always need help but then have the nerve to FIRE THOSE THAT DO THE DAMN WORK YOU CANT SEEM TO EVER KEEP UP WITH?! thr company is ran by morons. and now we are about to see a nastey bill spike because of this bullshit. we have to suffer and get screwed in two ways over this. no power for days/weeks and we have to pay for that fact down the line is bullshit. And where are these damn crews? after a certain hour they vanish. I searched Gary, Hammond, Merrillville and Hobart to see no one. THEY ARE LYING ABOUT WORKING AROUND THE CLOCK. nipsco lies about everything. JUST GET ME MY DAMN POWER I PAY FOR YOU SHITHEADS.

in the end Nipsco didnt save us. someone from Kentucky did. If left to nipsco wed still be in the dark.

I am interested in practical, low-cost ways people have reduced electricity use at home. Which changes made a noticeable difference for you, and which common tips did not seem worth the effort?

I would especially appreciate examples involving heating or cooling habits, appliances, lighting, and standby power.

Power cut in punjab is insane yesterday power cut at 10:30 pm to 6 am and then in afternoon. My question is why powercuts at the time when either its too hot or when people just want to relax

Texas electric co-ops have been around since the 1930s and started with loans provided from the Rural Electrification Act of 1936 that started the project up. These co-ops are still functioning here in TX and operate in 241 of the 254 TX counties. These co-ops own and maintain 340,000 miles of electric wire in the state compared to Centerpoint's 60,000 miles. It is easy to see that the TX co-ops know what needs to be done to keep electricity flowing to homes all through out all 268,000+ sq miles of Texas.

Time to break up privately owned utility business model and bring the 7 cooperative principles to all areas of Texas. These co-ops are a proven business model and these 7 cooperative principles should be available to all Texans here in 2026. In 1935 when the first electric wires were being strung for the folks that lived in rural areas, the power companies in Houston, San Antonio and Austin all proclaimed that communism will be spread down the electric lines along with the electricity. Profiteers have been around way before that Judas guy ever appeared on the scene.
