(i) A `3mu F` capacitor is charged up to 300 volt and `2mu F` is charged up to 200 volt. The capacitor are connected so that the plates of same polarity are connected together. The final potential difference between the plates of the capacitor after they are connected is :

Options

A. 600
B. 800
C. 700
D. 260

Explanation

To solve the problem, we need to find the final potential difference across the capacitors after they are connected with the same polarity plates together. Let's break it down step by step.

### Step 1: Calculate the charge on each capacitor before they are connected.

1. **For the 3 µF capacitor charged to 300 V:**
\[ Q_1 = C_1 \times V_1 = 3 \, \mu F \times 300 \, V = 900 \, \mu C \]
