Measuring Current with an Oscilloscope (Full Lecture)

ERROR at 30:40 Channel 2 has a peak to peak span of 6.4 divisions instead of 4.4 divisions. You should be obtaining the following values for channel 2: Vpp=64mV, Vp=32mV, Vrms=22.6mV, I=4.5mA/-81 This would also change the impedance calculations at 33:05: Z=1.2k/81, R=186.7, L=125mH. In this lesson we'll examine an indirect means of measuring and displaying current on an oscilloscope by using a small sensing resistor in series with a load impedance under inspection. Using this technique a technician can simultaneously display voltage across and current through an element. Various properties including relative phase shift can be measured using this technique.
