An electric bulb is rated as 250V, 750W. Calculate the
Resistance of its filament

Explanation

To calculate the resistance of the filament of the electric bulb rated at 250V and 750W, we can follow these steps:

### Step 1: Understand the relationship between power, voltage, and resistance
The power \( P \) consumed by an electrical device can be expressed in terms of voltage \( V \) and resistance \( R \) using the formula:
\[ P = \frac{V^2}{R} \]
Where:
