Problem

Which of the following expressions correctly represents the tangent of the phase angle

\phi

between the source voltage and circuit current in a series RLC circuit? a)

\tan\phi = \dfrac{X_L - X_C}{R}

\tan\phi = \dfrac{R}{X_L - X_C}

\tan\phi = \dfrac{X_L + X_C}{R}

\tan\phi = \dfrac{X_C - X_L}{R}
