A current of 2 A is passed through a coil of resistance 75 ohm for 2 minutes
How much heat energy is produced ?

Explanation

To find the heat energy produced when a current is passed through a coil, we can use the formula:

\[ H = I^2 \times R \times t \]

where:
- \( H \) is the heat energy produced (in joules),
- \( I \) is the current (in amperes),
- \( R \) is the resistance (in ohms),
