Question

76.How much energy is required by each

coulomb of charge passing through a 10

V battery?

A. 1 Joule

B. 12 Joule

C. 10 Joule

D. 5 Joule​

Answer 1

Ans. C

Sol. The energy required by each

coulomb of charge is equal to the amount

of work which is done in moving it.

So, work done = potential difference ×

charge

And it is given that,

charge = 1 coulomb

potential difference = 10 V

So from above expression, work done =

10 × 1 = 10 Joule.

Therefore, 10 J of energy is required by

each coulomb of charge passing through

a battery of 10V.
