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
