Electro Magnetic Induction And Alternating Currents Question 51

Question: A series ac circuit consist of an inductor and a capacitor. The inductance and capacitance is respectively 1 henry and 25μF. If the current is maximum in circuit then angular frequency will be [RPMT 1999]

Options:

A) 200

B) 100

C) 50

D) 200/2 π

Show Answer

Answer:

Correct Answer: A

Solution:

Current in LC circuit becomes maximum when resonance occurs.

So ω=1LC=11×25×106=10005=200,rad/sec
