An alternating emf source with a variable frequency f d connected in series with a 50.0 resistor

Question:

An alternating emf source with a variable frequency f d connected in series with a 50.0Ω resistor and a 20.0μF capacitor. The emf amplitude is 12.0 V.

(a) Draw a phasor diagram for phasor VR (the potential across the resistor) and phasor VC (the potential across the capacitor).

(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?
