An AC circuit has resistor, capacitor and inductor connected in series. It is
connected to a voltage supply at resonant frequency. If the frequency of the
voltage supply is reduced, which of the following quantities will be reduced? *

Respuesta :

Answer:

Z  = (R^2 + X^2)^1/2

At the resonant frequency, the quantity X equal zero and

w L - 1 / (w * C) equals zero where w is omega the angular frequency
