at high frequencies why the circuit will be more inductive than capacitive?

Expert Answer:

Dear Student

The impedance of an inductor is given by L*w, where L is the value of the inductor and w is the frequency.

And, the value of impedance of a capacitor is given by 1/C*w, where C is the capacitance and w is the frequency.

And impedance is bsically the resistance offered by the capacitor or the inductor to the flow of the current.

So, at high frequency, w is much much high, so it means that for an inductor the value of impedance is high and for the capacitor the value of impedance is less. So the value for capacitor tends to decrease and for the inductor , it tends to increase.

Hence the indcutor comes more effectivel than the capacitor.

We hope that clarifies your query.
