A resistor (R = 900 ), a capacitor (C = 0.25 湩), and an inductor (L = 2.0 H) are connected in series across a 240 Hz AC source for which Vmax = 140 V. Calculate values for the following.

---I only need help with part c----

c) the phase angle between the current and voltage

thank you so much!

If voltage is the reference, then

I=V/Z calculate Z in polar form

If voltage is the reference, then
