An Ac Generator Produces 10 V (Rms) at 400 Rad/s $\Omega$

Multiple Choice

An ac generator produces 10 V (rms) at 400 rad/s. It is connected to a series RL circuit (R = 17.3 $\Omega$ , L = 0.025 H) . The rms current is:

A) 0.50 A and leads the emf by 30 $\degree$
B) 0.71 A and lags the emf by 30 $\degree$
C) 1.40 A and lags the emf by 60 $\degree$
D) 0.50 A and lags the emf by 30 $\degree$
E) 0.58 A and leads the emf by 90 $\degree$
