question 285

Multiple Choice

The figure shows a series ac circuit. The inductor has a reactance of $60 \Omega$ and an inductance of 210 $\mathrm { mH }$ . A $30 - \Omega$ resistor and a capacitor whose reactance is $80 \Omega$ are also in the circuit, and the rms current in the circuit is $2.2 \mathrm {~A}$ . What is the phase angle of the circuit?

• A) \(- 56 ^ { \circ }\)
• B) \(+ 90 ^ { \circ }\)
• C) \(34 ^ { \circ }\)
• D) \(- 34 ^ { \circ }\)
• E) \(56 ^ { \circ }\)
