Electro Magnetic Induction And Alternating Currents Question 213

Question: Three oscillating LC circuit with identical inductors and capacitors. If t1 , t2 , t3 are the time taken by the circuits I, II, III for fully discharge, then

Options:

A) t1>t2>t3

B) t1<t2<t3

C) t2<t1<t3

D) t3=t1t2

Show Answer

Answer:

Correct Answer: C

Solution:

  • Time period, T1=2πLC,T2=2πLC2

    T3=2π2LC Clearly t2<t1<t3.
