Question

At resonance the power factor of a series rlc circuit is

Answer 1

Answer:

The resonance of a series RLC circuit occurs when the inductive and capacitive reactances are equal in magnitude but phase cancel each other because they are 180 degrees apart in phase. Under resonance condition equivalent impidence due to only resistor

Answer 2

Explanation:

Therefore, it makes no difference if the inductor or capacitor are connected in parallel or series. ... Thus at resonance, the impedance of the parallel circuit is at its maximum value and equal to the resistance of the circuit creating a circuit condition of high resistance and low current.
