We often use screw driver testers, where we touch one end of the screw driver with our finger and put the pointed end into the mains. The bulb inside the tester glows, indicating that the mains are active.
My question is, how is the circuit completed in this case? If charge flows from our body to ground, how does it go back to the 'source', which is the other pin of the mains power supply?
