Why we need a 5 A fuse for an electric iron which consumes 1 kW power at 220 V ?

Explanation

To determine why a 5 A fuse is needed for an electric iron that consumes 1 kW of power at 220 V, we can follow these steps:

### Step 1: Understand the relationship between power, voltage, and current.
The power consumed by an electrical device can be calculated using the formula:
\[ P = V \times I \]
where:
- \( P \) is the power in watts (W),
- \( V \) is the voltage in volts (V),
