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.
