In a series RLC circuit, the phase difference between the current in the circuit and the voltage across the resistor is?

A)
0⁰
B)
90⁰
C)
180⁰
D)
360⁰

Correct Answer : Option (A) :   0⁰

Explanation : In a series RLC circuit, the phase difference between the voltage across the resistor and the current in the circuit is 00 because they are in phase.
