Post Body

I was really curious about the power a test screwdriver consumes and the current through it.

I tested at 220v ac. The voltage across it is like 99% of the main with 1% through u. So that is also the difference in resistance I suppose. Well it's impedance in your body.

A good multimeter with a max range of 100Mohm can't get the resistance of the test screwdriver while my body measures 200kohm. And measuring current in Uamps didn't measuring.

I imagined milliamps and uamps at most . so wow...

I was testing if a digital gfci device I want to make will take effect with test screw driver. It seems No.
