Question:

A coil of 500 turns is threaded by a magnetic flux of $7 \times 10^{-5} Wb$. If the flux changes to $3 \times 10^{-5} Wb$ in 0.01 s, what average induced emf is developed in the coil? If resistance offered by the coil is $10 \Omega$, then the flow of average induced current will be:

Options:

3 V, 0.3 A

1 V, 0.2 A

2 V, 0.2 A

4 V, 0.1 A

Correct Answer:

2 V, 0.2 A

Explanation:

The correct answer is Option (3) → 2 V, 0.2 A
