An rlc circuit is composed of a 3.5 kω resistor, 1.1 nf capacitor and 7.6 mh inductor. if an ac 6.8 v rms is applied, what frequency (in hz) is necessary for the maximum power to be supplied to the circuit?

Hz

Explanation:

we know that the power is maximum in RLC circuit when inductive reactance and capacitive reactance are equal.

= Capacitance of the capacitor = 1.1 x 10⁻⁹ F

= Inductance of the inductor = 7.6 x 10⁻³ H

= frequency necessary for maximum power

=  capacitive reactance =

=  inductive reactance =

For maximum power :

=

=

Hz
