Parallel Plate Capacitor: Practice Problem & Solution

Choose the CORRECT statement :
C will increase on increasing Q
C will increase on decreasing Q
C will increase on decreasing V
C doesnot depend on Q & V

Solution Explained:

To solve this problem, we apply the core principles of Parallel Plate Capacitor. Understanding the underlying formula is key to arriving at the correct answer below:

The capacitance of a capacitor is a constant determined by its geometric shape, size, and the medium between the plates. It is independent of the charge \( Q \) and potential difference \( V \) applied to it.
