A current of 0.2 A flows through a wire whose ends are at a potential difference of 15 V. Calculate :
the resistance of the wire,

Explanation

To solve the problem of finding the resistance of the wire, we will use Ohm's Law, which states that:

\[ V = I \times R \]

Where:
- \( V \) is the potential difference (voltage) across the wire,
- \( I \) is the current flowing through the wire, and
- \( R \) is the resistance of the wire.
