The current through tungsten filament lamp connected to a 12 V accumulator of negligible resistance is 3.0 A. Calculate :
the electrical energy in kWh consumed in 5 hours

Explanation

To solve the problem of calculating the electrical energy consumed by a tungsten filament lamp connected to a 12 V accumulator over a period of 5 hours, we will follow these steps:

### Step 1: Identify the given values
- Voltage (V) = 12 V
- Current (I) = 3 A
- Time (t) = 5 hours

### Step 2: Use the formula for electrical energy
