Tips: Can an oscilloscope measure current?
Most oscilloscopes only directly measure voltage, not current, however, you can measure current with an oscilloscope, using one of two methods. Measure the voltage dropped across a shunt resistor: Some power supply designs may have shunt resistors built into the design for feedback.
