Measurement AC current with Oscilloscope
mostly the oscilloscope used to measured voltage, whereas to measure current (on Alternating Current) else can. the trick is measure voltage drop passed through in shunt resistor. When voltage drop passed through on shunt resistor be measured, that’s proporsional with current amount passed through in resistor.
see follow below the pictures:
Actually, from above picture at great risk if used direct a osiloskop. To be safe, use voltmeter, suchh as the following shematic:
