The other day I was experimenting with a multimeter and checked the voltage in one of the electric plug at home. Without surprise I measured around 230V between phase and neutral and also 230V between phase and earth (By earth, I mean the earth wire, the "3rd hole").
Then I tried the measure the voltage between phase and my body by sticking one probe in the phase hole and holding the other in my hand (Might not be the best idea if the meter as a failure or is set to measure current instead of voltage... did it nevertheless...). There I measured around 8V AC. Why ? The voltage between me and the earth should be almost 0V hence the potential difference between me and the phase should be around what I measure between phase and earth wire (230V). Which make sense since if I stick my finger in the plug I'm sure I'll get a nice full 230V shock. So why does the meter indicate such low voltage ?
My guess is that it has something to do with capacitance since Earth (big 'E') capacitance is much higher than my body capacitance and would therefore allow higher alternating current to flow in it than into my body ? (Really fuzzy guess sorry).
Thanks for you help :)
