Solution:
Given:
Potential difference (V)= 15 V
Charge (Q)= 3C
We know that
The potential difference(p.d) between two point in an electric circuit is defined as the amount of work done in moving a unit charge from one point to the other point.
Potential difference (V) = work done (W)/Charge (Q)
V= W/Q
Putting the values in the above formula we get:
15 V = W / 3 C
W= 15 V × 3 C
W= 45 J
Hence, the work done in moving the charge is 45 J.

Answer:
Charge = 3Coulomb
Voltage = 15 volt
We know that the formula of W = V × Q
Putting the values in this formula
W = 15 × 3
W= 45 Joules...
hence, solved.
