Question

1. in an rl series circuit, as the phase angle approaches 0 degrees, the circuit is mostly

inductive

resistive

capacitive

neither, r and l are balanced (equal)

Explanation:

In an RL series circuit, the phase angle formula is $\varphi=\arctan(\frac{X_{L}}{R})$. When the phase angle $\varphi$ approaches $0$ degrees, $\tan\varphi$ approaches $0$. Since $\tan\varphi=\frac{X_{L}}{R}$, this means $X_{L}$ approaches $0$ compared to $R$, so the circuit is mostly resistive.

Answer:

B. resistive
