Answer:
Explanation:
Given
In R-L-C circuit frequency is very high
Inductive Reactance for inductor is given by
Inductive Reactance for Capacitor is given by
as frequency becomes too high then will become very large and and
will be approximately zero .
In other words inductor behave as a very high resistance and Capacitor behaves as very small resistance
