Answer to Question #74631 in Electric Circuits for Pkm

Question

In L-C-R circuit, the current and voltage are in same phase only at a single
frequency. state true or false, also give a reason of your answer .

Answer 1

At resonance a circuit's net reactance equals to zero ohms and the net impedance is all resistive . Therefore the phase difference between current and voltage is 0 degrees
So, the statement is true.
