Question

How is Mutual Induction fundamentally different from Self Induction?
Options
A Mutual induction occurs with AC currents, while self induction occurs with DC currents.
B Self induction is a characteristic of a single coil, while mutual induction is a characteristic of a pair of coils.
Correct Answer
C Mutual induction opposes current decay, while self induction opposes current growth.
D Self induction leads to energy loss, while mutual induction improves efficiency.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The table on page 38, 'Difference between Self and Mutual Inductance', clearly states: 'Self inductance is the characteristic of the coil itself.' and 'Mutual inductance is the characteristic of a pair of coils.'

Hint

Consider the number of coils involved in each phenomenon.
