A resistor of 6 `Omega ` is connected in series with another resistor of 4 `Omega `. A potential difference of 20 V is applied across the combination. Calculate :
the potential difference across the 6 `Omega ` resistor.

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Identify the resistors and their values
We have two resistors in series:
- Resistor R1 = 6 Ω
- Resistor R2 = 4 Ω

### Step 2: Calculate the equivalent resistance
