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.
The oscilloscope can be used to get the resistance of a resistor. However, the downside is that it requires additional steps, such as having another resistor with known value, and a DC power supply. Higher resistance may require higher voltage without using an opt amp to avoid measuring in micro volts…
