PhysicsEMI/ACAC current and voltageEasy2 minPYQ_2008
PhysicsEasysingle choice
Assertion : The alternating current lags behind the e.m.f. by a phase angle of , when AC flows through an inductor. Reason : The inductive reactance increases as the frequency of AC source decreases.
Options:
Answer:
C
Solution:
Assertion is correct but reason is false because inductance reactance . So, higher frequency greater inductance reactance.
