Hello Forum,
I have an old analog oscilloscope. The probes have a ground clip that should be attached to the ground, reference conductor in the analyzed circuit. What if I don't connect that ground probe to the circuit ground? The oscilloscope also has a ground and a waveform is traced on the scope screen anyway, correct? Does it mean that we are using the ground point for the oscilloscope which can be at a different potential than the ground in my analyzed circuit?
I get often confused with the different types of ground that can occur in a circuit (floating, mass, etc.) I know that voltage is always measured between two different physical points. One of the points (conductors) in the circuit can be elected to be the ground and the potential of all other points can be higher (positive) or lower (negative) than that reference point....
Thanks,
Spacerat
