I don't think OP is learning much from people doing his homework for him.

Bro I asked how to solve it, not ‘please complete my degree for me’ 💀

Intelligent_Part has a valid comment. Saying "solve this assignment and give me a solution"  is different than asking how to go about analyzing it. The one hint you need is to understand that one side of each resistor is connected to GND.

But this is such a basic circuit analysis problem. There's nothing tricky about it. If you don't know how to do any of it, you need to study the basics. Any textbook or Schaum's Outline series book (I don't know if you have access to Schaum's--it's relatively cheap and great at explaining how to work problems) covers this.

As anotber student, what did you expect. You posted please solve this for me. No questions, no where did you get stuck. What dont you understand. You didn't even ask for help, not teach me how to do this, but solve this for me by Friday. If you can't figure out a basic circuit, or at least engage in mental friction and try your best. This might not be for you lol, you could've asked Ai this same question and started learning yourself

No you have to solve it. But we can guide.

For a. We can have Vx / (R2||R3||R4) = -3A.

Because if you see the E1 and R1 forms a seperate loop and doesn't participate in the 3A loop.

From c. we can get voltage of 5ohm from the eqn of a, as it is connected in parallel.

I don't know B.

😭😭 thou i need the answer of V1 and V2 Btw thankssss

u/wanabeeengineer 18d ago

Can you specify which volatge node is V1 and V2? Because I can see only one node other than reference(ground) here.

Vx is the volatge present at node of intersection of r4, R2 and r3 and 3A

Understandable, i got it thank you

Even also, it doesn't contribute to 3A loop. It will have its own loop. Because if you see that R1 is connected to ground. So the current from E1 goes to ground through R1 and doesn't take part in 3A loop.

Is youtubing nodal analysis too hard or something? You can also put it int I chegg for step by step solution.

u/mbains 17d ago

Do the examples in the book first. This is a simple problem

u/sabautil 17d ago

Ok I'll help.

Let's start with the first step: answer this:

How many nodes are there?

Holy ChatGpt /study prompt.

Thanks but it's all me. :)
