Hello everyone!
I am new to electronics and am working on an associates program as a means to expand my knowledge. I come from a background in Chemistry so I'm all stuck in my head about reactions going to an "equilibrium".
In the case of my question in the subject line, I was reviewing Chapter 3 in the All About Circuits textbook regarding electrical safety and shock path. In the example of a person touching an un-grounded circuit, the author details that ideally a grounded person can touch any portion of the circuit without getting shocked (ideally). I understand that in order for current to flow, there needs to be a complete path through a circuit, which the person is not a part of.
That being said, as I understand from the book, voltage is the potential energy caused by the separation of charge. If ground is our reference for "0V", then wouldn't there be a difference in voltage should you be touching the positive terminal of a voltage source? In that case wouldn't current flow through you to ground in an attempt to balance the charge?
