Question

How much work is done in moving a charge of 4c across two points having difference of 12 v? Calculate the no of electrons
​

Answer 1

Work is done in moving a charge of 2 coulomb across two points having a potential difference of 12 volt is 24 joule .

Step-by-step explanation:

Formula

W = qV

Where q is charge , W is the workdone and V is the ponential difference .

As given

work is done in moving a charge of 2 coulomb across two points having a potential difference of 12 volt .

q = 2 coulomb

V = 12 volt

Put all the values in the formula

W = 2 × 12

W = 24 joule

Therefore the work is done in moving a charge of 2 coulomb across two points having a potential difference of 12 volt is 24 joule .
