Inductor Voltage-current Relations

Starting lab...
                 This lab is almost same with previous lab "Capacitor Voltage-current Relations", but we change capacitor with inductor and measure same thing in 3 voltage sources.
1kHz, 2V Sinusoidal input Voltage

2kHz, 2V Sinusoidal input voltage

100Hz, 4V triangular input voltage
Summary: It makes sense that all of voltage across inductor is very low because inductors resist change in voltage. So Voltage across them are low compare to input voltage. This lab I think we also messed up the input equation of current, or it might be very low. As for voltage in triangle wave, I think because the amplitude of wave is high again, so inductor want to resist its high slope of change and thus have very low voltage across it.
