Electro Magnetic Induction And Alternating Currents Question 46

Question: In the non-resonant circuit, what will be the nature of the circuit for frequencies higher than the resonant frequency [RPET 1996]

Options:

A) Resistive

B) Capacitive

C) Inductive

D) None of the above

Show Answer

Answer:

Correct Answer: B

Solution:

In non resonant circuits impedance $ Z=\frac{1}{\sqrt{\frac{1}{R^{2}}+{{( \omega C-\frac{1}{\omega L} )}^{2}}}} $ , with rise in frequency Z decreases i.e. current increases so circuit behaves as capacitive circuit.
