A 100 W heater coil is rated 200 V. Find the resistance of thwe coil.

Explanation

To find the resistance of a heater coil rated at 100 W and 200 V, we can use the formula for electrical power:

\[ P = \frac{V^2}{R} \]

Where:
- \( P \) is the power in watts (W)
- \( V \) is the voltage in volts (V)
- \( R \) is the resistance in ohms (Ω)
