question 364

Multiple Choice

A series circuit has a $50 - \mathrm { Hz }$ ac source, a $40 - \Omega$ resistor, a $0.70 - \mathrm { H }$ inductor, and a $60 - \mu \mathrm { F }$ capacitor, as shown in the figure. The rms current in the circuit is $1.6 \mathrm {~A}$ . What is the voltage amplitude of the source?

• A) \(190 \mathrm {~V}\)
• B) \(220 \mathrm {~V}\)
• C) \(270 \mathrm {~V}\)
• D) \(330 \mathrm {~V}\)
• E) \(390 \mathrm {~V}\)
