In charging a capacitor of capacitance C by a source of emf V, energy supplied by the sources QV and the energy stored in the capacitor is ` 1//2 QV`. Justify the difference.

Explanation

To justify the difference between the energy supplied by the source (QV) and the energy stored in the capacitor (1/2 QV), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Charging Process**:
- When a capacitor of capacitance \( C \) is charged by a source of emf \( V \), charge \( Q \) is supplied to the capacitor. The relationship between charge, capacitance, and voltage is given by:
\[
Q = CV
