Question

Assertion : The alternating current lags behind the e.m.f. by a phase angle of π/2. when AC flows through an inductor.

Reason : The inductive reactance increases as the frequency of AC source decreases.

(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 correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option (c) A is true but R is false

Explanation:

Assertion is correct but leason is false because inductance reactance X_L = 2πfL . So, higher the frequency greater will be the inductive reactance.
