| Feb 8, 2022 at 7:31 | comment | added | MSKB | if we just focus on the rightmost loop, then potential drop across 6ohm was supposed to be 18V and so potential at that terminal should be 30V-18V=12V then we have 15V at the junction. As current cannot flow back to positive terminal of 30V source due to higher potential than 15V, So it will flow towards negative terminal then we have a 12Vvoltage drop across 4ohm. which means we are remaining with 3V at b. as far as I know potental at point b should be zero as a portion of the electrons goes to a reference potential region which is 0V and there are no resistance to drop some potential. | |
