Potential difference/resting potential?

[futureless]

Hi, I'm not sure if I posted this in the right place, so sorry if I'm completely wrong.

I had Biology today and the term potential difference cropped up when we were talking about resting potential and I was thinking "What on earth...":eek: .

Isn't p.d a fancy word for voltage which is the drivinhg force of electrons round a circuit? What has it got to do with polarised membranes?

perhaps it was in reference to Osmotic pressure?

Google is your friend, and all roads seem to lead to wikipedia.
