PHYS345 Electricity and Electronics

Answer for E8-1

The result of rationalizing Eq.1 is:
Gv = G0(1-jx)/(1+x2) where x = f/fu has been introduced as a dimensionless frequency.

This expression is now in standard form and the phase angle may be extracted from the imaginary and real parts:
tan(phase angle) = Im{Gv}/Re{Gv} = -x.

Find the phase angle for x = 0.5, 1.5, 2.5, and infinity.
