An alternating emf source with a variable frequency f d is connected in series with an 80.0

Question:

An alternating emf source with a variable frequency f d is connected in series with an 80.0Ω resistor and a 40.0 mH inductor. The emf amplitude is 6.00 V.

(a) Draw a phasor diagram for phasor V R (the potential across the resistor) and phasor V L

(the potential across the inductor).

(b) At what driving frequency f d do the two phasor have the same length? At that driving

frequency, what are?

(d) The angular speed at which the phasor rotate, and

(e) The current amplitude?
