Question

calculate the work done in moving a charge of 4 ampere across a potential difference of 5 volt​

Answer 1

Work done on a moving charge is given by the formula

W=Q∆V

W=5×4

W=20

I hope this helps ( ╹▽╹ )

Answer 2

Answer:

W=V×Q and V is 5 volt and in question a charge means 1 coulamb charge then W=5×1 then W is 5 joule
