Question

how much work is done in moving a charge of 3C from a point of 38 volts to point at 48 volts

Answer 1

work done,W=V*Q(volt in coulomb)
for 38 volts
W1=38*3
=114 joules
for 48 volts
W2=48*3
=144 joules
Therefore work done in moving a point 38 volts to 48 volts is=W2-W1
=144-114
=30 joules
Thank you
