Disclaimer: Some parts of this circuit carry dangerous Mains voltage. If you are a beginner, seek guidance from experienced users.
Dealing with the 110V/220V AC mains voltage and measuring the AC load parameters are regarded as a challenge for electronic designers, both in circuit design and...
Measuring the AC current (220V mains RMS current) is not as simple as measuring the DC current. In the DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the voltage difference and the current, however, that is not the case with the mains line...
