Physically, the self-inductance plays the role of
- A inertia
- B kinetic energy
- C potential energy
- D velocity
Answer & Solution
Correct Answer
(A) inertia
Step-by-step Solution
Detailed explanation
Physically, the self inductance plays the role of inertia. It is the electromagnetic analogue of mass in mechanics. So work needs to be done against the back emf in establishing the current.
