NEET Physics Self & Mutual Induction MCQ Question
Which of the following statements about self and mutual induction is correct?
Self-inductance is analogous to inertia in mechanics and opposes changes in current.
Mutual induction occurs only when two coils are not in proximity to each other.
The self-induced emf always increases the current in the circuit.
Self-inductance is independent of the geometry of the coil and the medium's permeability.
Correct Answer
Detailed Explanation
Self-inductance acts like inertia, opposing any change in current as stated in the NCERT context. The back emf opposes current changes, similar to how mass resists acceleration in mechanics.
