A torch bulb is rated 5 V and 500 mA. Calculate Its
Resistances

Explanation

To calculate the resistance of the torch bulb, we can use Ohm's Law, which states that:

\[ V = I \times R \]

Where:
- \( V \) is the voltage (in volts),
- \( I \) is the current (in amperes),
- \( R \) is the resistance (in ohms).
