`100 J` of heat are produced each second in a `4 Omega` resistance. Find the potential difference across the resistor.

Explanation

To solve the problem, we need to find the potential difference across a resistor given the heat produced and its resistance. Here’s a step-by-step solution:

### Step 1: Identify the given values
- Heat produced per second (Power, P) = 100 J/s = 100 W (since 1 J/s = 1 W)
- Resistance (R) = 4 Ω

### Step 2: Use the formula for power in terms of voltage and resistance
The formula relating power (P), voltage (V), and resistance (R) is given by:
