    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
