Question

calculate the work done in moving a charge of 4 coulomb from a point of 220 volt to another point at 230 volt

Answer 1

HEY DEAR ... ✌

____________________________


potential difference ( V ) =10 V  [230 V - 220 V ]
charge ( Q ) =    4C
work done = charge * potential difference
10 V * 4C = 40 J


HOPE , IT HELPS ... ✌

Answer 2

Hi,

Here is your answer

Given charge  = 4 C
The potential at one point = 220 V
Potential at another point = 230 V
Potential difference = 230 - 220 = 10 V

Work done = potential difference * charge
                    = 10 V*4 C
                    = 40 J

Hope this helps you.
