thanks for your reply, I've heard the gravtiational analogy before
the thing on my mind is, if the charge/electrons have more potential energy before a component than after (resulting in a pd) then in what form do they have that energy?
to return to the gravitational energy analogy, then an...
could anyone shed some light on the following...
the language might not be too precise here, but I'm trying to get a feel for the subject
in a battery one terminal (metal) has an excess on electrons which have come from the other +ve terminal (metal), this causes a difference in potential...
thanks doc al, i suspected it could be this something like this, so you could kind of say temperature is measure of the mayhem going on around you when you're sat in the middle of things
hello, my first post here, I'm training as a physics teacher and my physics is quite rusty, it's been a good few years since university, i was thinking about heat (of air for example) being the kinetic energy of the particles and then i thought if that was the case wouldn't a mass of air with a...
