A capacitor of `20muF` charged upto 500 V is connected in parallel with another capacitor of `10muF`, which is charged upto 200 V. the common potential is

Options

A. 400 V
B. 300 V
C. 200 V
D. 100 V

Explanation

To find the common potential when a capacitor of \(20 \mu F\) charged to \(500 V\) is connected in parallel with another capacitor of \(10 \mu F\) charged to \(200 V\), we can follow these steps:

### Step 1: Calculate the charge on the first capacitor
The charge \(Q_1\) on the first capacitor can be calculated using the formula:
\[ Q_1 = C_1 \times V_1 \]
Where:
