Question

Calculate the work done in moving a charge of 5 coulombs from a point at a potential of 20volts to another point of 240 volts

Answer 1

Potential difference=work done/charge moved
V=W/Q
Potential difference=(240-20)volts
=220 V
Work done,W=?
Charge moved,Q=5 coulombs
Now,
220=W/5
Hence,W= (5×220) joules
1100 joules
