question 81

Multiple Choice

The figure shows a series ac circuit. The inductor has a reactance of $60 \Omega$ and an inductance of 150 $\mathrm { mH }$ . A $50 - \Omega R$ and a capacitor $C$ whose reactance is $90 \Omega$ are also in the circuit, and the rms current in the circuit is $1.5 \mathrm {~A}$ . What is the rms voltage of the source?

• A) \(81 \mathrm {~V}\)
• B) \(75 \mathrm {~V}\)
• C) \(78 \mathrm {~V}\)
• D) \(84 \mathrm {~V}\)
• E) \(87 \mathrm {~V}\)
