A $120 - \mathrm { V }$ rms voltage at $60 \mathrm {~Hz}$ is applied across an inductor and a $200 - \Omega$ resistor. If the impedance of this circuit is $216 \Omega$, what is the rms value of the current?
A) $0.667$ A
B) $0.336 \mathrm {~A}$
C) $0.767$
D) $0.446 \mathrm {~A}$
E) $0.556 \mathrm {~A}$
