I have a simple inductor circuit shown here:
I calculated the voltage drops for R1, L1, and L2. For my calculations I calculated:
R1 = 8.23 VP-p @ -34.65 degrees
L1 = 6.17 VP-p @ 55.35 degrees
L2 = 515 mVp-p @ 55.35 degrees
When I add all those up, I get about 10 VP-p with pretty close to 0 degrees phase, so I'm happy.
I decided to build the circuit to see what my actual measurements would be.
For R1 I measured about 8.22 VP-p, but my phase shift is at about -55 degrees. For my L1 and L2, I hardly see any phase shift on the circuit. I understand that there will be differences between calculated values and measured values, but to me this seems like a pretty huge difference.
This is a picture of how I built my circuit while looking at R1. The channel 1 probe is on the left and the channel 2 probe is on the right attached to the resistor.
This is a screen shot of what I'm reading on my oscilloscope.
I must be doing something wrong, or not understanding something correctly. Any help would be appreciated.
