Question

how much work is done in moving a charge of 9 c across two points having potential difference of 12 v​

Answer 1

Answer:

work done(w)= potential diff(v) × charge(Q)

w=v×Q (v=w/Q)

w=12×9

w= 108 J

Answer 2

Given,

Charge , q = 9 C

Potential difference = 12 V

We know,

$V=\frac{W}{q}$

∴ Work done = V . q

                         = 12×9

                         = 108  J

INFORMATION :

The electric potential at a point in an electric field is the amount of work done in moving a unit positive charge from infinity to any point against the electrostatic forces.
