15.5 Exercise 3

Avg difficulty 2.5

The resonant angular frequency of an RLC series circuit is 4.0×102rad/s.4.0 \times 10^{2} \text{rad}/\text{s} . An ac source operating at this frequency transfers an average power of 2.0×10−2W2.0 \times 10^{−2} \text{W} to the circuit. The resistance of the circuit is 0.50Ω.0.50 \Omega . Write an expression for the emf of the source.
