Hi, why do I keep getting a voltage of 60mV across the inductor in the following series RL circuit:
Resitor: 2.2k
Inductor: 8.2mH
AC source: 13 volts at 0 degrees
The voltage across inductor is supposed to be 18.27mV at an angle of 89.92, with a circuit current of 5.91mA at -0.08051 deg.
However, when I connect my 10meg digital voltmeter I keeep getting about 60mV.
-----------------------
I have a theory, but I'm not sure. I think the voltage might be unmeasurable with voltmeter due to the fact that it is 89.92 degrees ahead of the current....
Also what I´m probably getting is the current multiplied by 10: 5.91 x 10 = 59.1mA, which is what the voltmeter is probably picking up as voltage across inductor.
---Please, any help.
