Consider the following circuit:

For the above circuit, which one of the following statements is correct? The voltage V0 is independent of R, if the input signal frequency —

1. is 1
  LC
2. is 1
  [2 LC]
3. is LC
4. has any value

Correct Option: A

V₀ should be independent from R when no current in R. It will be possible when R → ∞ or there should be series resonance in LC circuit with adding resistance Condition of series resonance,

Z = R₁ + j		ωL -	1		= J		ωL -	1		= 0
			ωC					ωC

ω² =	1
	LC

or ω =	1
	√LC

is	1
	[2 LC]
