Question

Transcribed Image Text:A resistor and inductor are connected in series across an ac generator. The voltage of the generator is given
by V(t) = Vo cos(wt), where V
is the magnitude of the impedance of the LR circuit? (b) What is the amplitude of the current through the
resistor? (c) What is the phase difference between the voltage and current?
120 V, w
120n rad/s, R= 650N, and L = 3 H. (a) What
Hint
a. The magnitude of the impedance is
Ω.
b. The amplitude of the current through the resistor is
mA.
c. The phase difference between the voltage and current is
rad. (Take the
positive phase difference to mean that voltage is leading the current by this phase difference.)
