Question

For an RLC circuit in the limit of very high frequency, what is the effective behavior of the capacitor and the inductor in the circuit?

Answer 1

Answer:

Explanation:

Given

In R-L-C circuit frequency is very high

Inductive Reactance for inductor is given by $X_L=2\pi f\cdot L$

Inductive Reactance for Capacitor is given by $X_c=\frac{1}{2\pi f\cdot C}$

as frequency becomes too high then $X_L$ will become very large and and $X_c$will be approximately zero .

In other words inductor behave as a very high resistance and Capacitor behaves as very small resistance
