Final answer:
The resonant frequency of an RLC circuit is the frequency at which the reactances of the inductor and capacitor cancel each other out, resulting in minimum impedance. Increasing the value of the capacitance or inductance in an RLC circuit will decrease the resonant frequency, while increasing the resistance will have no effect on the resonant frequency.
Step-by-step explanation:
An RLC circuit is a circuit that contains a resistor (R), an inductor (L), and a capacitor (C) connected in series. The resonant frequency of an RLC circuit is the frequency at which the reactances of the inductor and capacitor cancel each other out, resulting in minimum impedance.
Increasing the value of the capacitance or inductance in an RLC circuit will decrease the resonant frequency, while increasing the resistance will have no effect on the resonant frequency.
