Question

Write the formula for capacitance of parallel plate capacitor. What effect does the area of the plates have on capacitance?

✓

Answer

Capacitance of parallel plate capacitor $C=\frac{\epsilon_0 A}{d}$
It is clear from the equation that the capacitance of a parallel capacitor is proportional to the area of the plates and inversely proportional to the distance between them. Capacitance can be increased by increasing the area A of the plates.
