Phase Angles: Consider a series circuit in which the capacitive reactance equals the inductive reactance. What is the phase angle between current and voltage for this circuit

X = R,   therefore the current and the voltage are in phase, that is, the angles are zero

Explanation:

In circuits with capacitors and inductors the phase between current and voltage varies according to frequency , capacitance and induction values, but they go in opposite directions. The first creates a delay in the current and the second an advance.

   If it is an RLC type serial circuit, the impedance is

            X = √[ R² + (XL- Xc)²

with

    XL = wL

    Xc = 1 / wc

let's apply this to mention if XL = Xc, the impedance the circuit is resistive

             X = R

therefore the current and the voltage are in phase, that is, the angles are zero

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
