In a parallel circuit, ET = 120 V, R = 30 Ω, and XL = 60 Ω. What is the phase angle (angle theta)?

sweet-ann [11.9K]

Phase angle (∅) in a parallel RL circuit is given by the formula; tan∅ $= \frac{I_{L} }{I_{L}}$

where $I_{L}$ is current through the inductor and given by $I_{L} = \frac{voltage}{X_{L}}$

and $I_{R}$ is current through the resistor and given by $I_{R} = \frac{voltage}{R}$

hence, tan∅ $= 30/60$ or ∅ = 26.565 degree
