Find the potential of J with respect of G :-(1) 40 V(2) 60 V(3) 20 V(4) 30 V55.60 V64 Q32 2 |

Answer» Let the current flowing in the resistance be i so, Potential difference is 60-0 = 60v ( because at G wire is grounded hence potential is 0) now total resistance = 64+32 = 96 so, i = v/R = 60/96 = 5/8 A potential at J = iR1 = 5/8*(64) = 40v so, difference is = 40-0 = 40V option 1 |
