A parallel plate capacitor has plates of area `4 m^2` separated by distance of 0.5 mm. The capacitor is connected across a cell of emf 100 V.
Find the capacitance, charge and energy stored in the capacitor.

Explanation

To solve the problem step by step, we will calculate the capacitance, charge, and energy stored in the capacitor.

### Step 1: Calculate the Capacitance (C)

The formula for the capacitance of a parallel plate capacitor is given by:

\[
C = \frac{A \cdot \varepsilon_0}{d}
