PHASE RELATIONS IN AC CIRCUITS
APPARATUS
60 mH inductor 214-01-D
1 uF capacitor 101-09-G4
decade resistor 214-01-A
function generator 202-08-G
audio transformer 214-01-D
oscilloscope with video camera 202

DESCRIPTION
Short out L or C to observe RC or RL circuit.  Show phase relations and change in relative amplitudes with frequency.
 
NOTES

Start with decade resistor set to 10 k.

Internal resistance of inductor is 6 ohms.

Trigger on signal generator output.
Or use the 4-channel digital storage scope to show three signals at once.
Here,
Vin is yellow,
VR is red,
VL is purple,
