Phasors: Passive RL Circuit Response

In today's lab, we will be concerned with the steady-state response of electrical circuits to sinusoidal inputs. We will measure the gain and phase responses of a passive RL circuit and compare these measurements with the calculations. 

 For w = 4, we found Zr = 10, Z1H = 4j, Z0.5H = 2j, Z 0.1F = -2.5j
We found Ix = 7.5<108.43

The picture shows the calculation is correct, at this frequency.
w = wc.
