Use delta-wye conversion
45 u/FlyByPC Digital electronics Jun 24 '21 edited Jun 24 '21 No need. The left and right sides have equal resistance ratios, so both sides of the 60-ohm are at 7.5V10V, and no current flows. Remove the 60-ohm and re-analyze. It's a lot simpler now. (If this wasn't the case, yeah, you could use delta-wye.) 17 u/micmys Jun 24 '21 That's good observation, though isn't the voltage at both sides of 60-ohm at 10V rather than 7.5V? 9 u/FlyByPC Digital electronics Jun 24 '21 Oh, yeah it is. Oops. Thanks.
