A bulb is connected to a battery of p.d. 4 V and internal resistance 2.5 `Omega `. A steady current of 0.5 A flows through the circuit. Calculate :
the total energy supplied by the battery in 10 minutes,

Explanation

To solve the problem, we need to calculate the total energy supplied by the battery in 10 minutes. Here’s the step-by-step solution:

### Step 1: Identify the given values
- Potential difference (V) = 4 V
- Internal resistance (r) = 2.5 Ω
- Current (I) = 0.5 A
- Time (t) = 10 minutes
