The work done per unit charge is 24 joule
what is work done?
Measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
The potential difference across the two points is directly proportional to the work done per unit charge.
V=W/Q
where,
V=potential difference
W=work done
Q=charge
W=Q×V
given:
Q=2 coulomb
V=12 volt
W=2×12
W=24 joule
