This question already has an answer here:
I am doing some measurement on Scope ( non-isolated) , my set up is like this -Scope is connected to 230V line mains with only two pin plug ( Earth or ground not used) -channel is connected with voltage probe -None of probe is hooked to any measurement point yet.
I observer when I touched any probe positive lead, I saw some high voltage waveform on screen,
a) First case :- I am reading 240Vac peak to peak and 82 Vrms on scope also can see sine wave on screen . I was sitting on chair , any I wore shoes and my shoes touching to ground.
b) First case :- I am reading 170Vac peak to peak and 50 Vrms on scope also can see sine wave on screen . I was sitting on chair , any I lift my legs form ground.
Q1) Is everything is right with setup
Q2) is it true voltage , then why i am not getting shock by touching probe lead
Q3) Why voltage shown when I am touching the lead, does I am generating the voltage from my body.
