As the frequency of an ac circuit increases, the current first increases and then decreases. What combination of circuit elements is most likely to comprise the circuit ?

A

Inductor and capacitor

B

Resistor and inductor

C

Resistor and capacitor

D

Resistor, inductor and capacitor

Text Solution

Verified by Experts

The correct Answer is:
1,4
We know that,
`I = (V)/(sqrt(R^(2) + (X_(L) - X_(C ))^(2)))`
`X_(L) = 2 pi upsilon L` and `X_(C ) = (1)/(2 pi upsilon C)`
So with increase in frequency, `R` remains constant, inductive reactance increases and capacitive reactance decreases.
