| Assertion (A): Self-inductance may be called the inertia of electricity. |
| Reason (R): Due to self-inductance, opposing induced e.m.f. is generated in a coil as a result of change in current or magnetic flux linked with the coil. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true but R is NOT the correct explanation of A
C) A is true but R is false
D) A is false and R is true
Correct Answer: B
Solution :
Option [b] is correct Explanation: Inertia is defined as the tendency of an object to resists its change of state of motion. Induced e.m.f. in a coil is changed by the change in current or magnetic flux. The property by which a coil opposes these parameters to incur any change in induced e.m.f. is known as self-inductance. Hence, self-inductance may called the reason both are true but reason connot explain why so happens.
