His explanation is right, it just kinda defeats the point of keeping it short and simple. A live conductor isn't actively pushing against anything, it's just waiting to touch something with a lower potential to equalize. But, when visualizing how a tool works or how a battery discharges at the layman level, it's not meaningfully different from hydraulic pressure.
Sorry electrical engineer here, my chances to put my knowledge in any general conversation is close to zero, need to jump when I can! People's response to finding out that information is generally to talk to someone else, rather than ask follow up questions. >.>
My first thought of pressure was like air or water which is basically intrinsic to the surrounding. Whereas potential requires an external force to activate (for voltage this "completing the circuit" (i.e. plug it in, turn it on)). Didn't really think about hydraulics. Like i said nitpicky anyways.
This is a thread that I found on another website I post at. It can be really really interesting. I thought it deserved a place here.
Post your random thoughts for the day here, or anything else that intrigues you.
For starters, is it possible to give constructive critism to someone who doesn't have a neck? I totally just walked by a girl who didn't. Someone isn't getting a necklace for Valentines day!
And who decided black and white can't be colors? I want to say a racist. I really do.
