Networks Analysis and Synthesis - Engineering

Q1:

Assertion (A): When excited by a unit step voltage, an inductor behaves as open circuit at t = 0. Reason (R): Inductance has the property of inertia.

A Both A and R are true and R is correct explanation of A

B Both A and R are true and R is not the correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:A - Both A and R are true and R is correct explanation of A

Because of inertia the current cannot change instantaneously. Therefore it behaves as O.C. at t = 0.
