Z Diagram of Low Pass Filter
I am to draw an impedance diagram of a low pass filter comprising resistor &
capacitor, and to indicate the phase angle. I am in dispute with teacher on
the phase angle.
Is the phase angle found by:
1) -arctan(wRC)
or
2) -arctan(Xc/R)
Appreciate if someone could advise which one of the above is correct.
TIA
