calculate the amount of work done to carry 4c of charge from the point at 100v to 120v
Hint:W=Q/I
i did it by this method....V=J/C
J=VC
here potential difference(V)= 120v-100v
therefore, V= 20V
J= 20*4
J=80
therefore 80 J of work is done
J=VC
here potential difference(V)= 120v-100v
therefore, V= 20V
J= 20*4
J=80
therefore 80 J of work is done
