Electric Potential Difference (2 Viewers)

[mrs_missile]

Dotpoint-
describe electric potential difference
(voltage) between two points as the
change in potential energy per unit
charge moving from one point to the other (joules/coulomb or volts)

Can someone please explain electric potential difference in simple words
Thanks

Electric Potential difference is the voltage/electromotive force. V is the potential difference. That is the dead simple meaning.
Also, Potential difference can be considered as the "energy applied per unit charge" (where the charge is the electron).

P = VI, E = Pt = VIt

I = Q/t E=QV

Therefore, V=E/Q which is in J/C which is in V.

Just want to get some terminology right. Energy is not 'applied'. Energy is acquired (or transformed) due to WORK done. The potential difference BETWEEN TWO POINTS is the WORK DONE BY THE ELECTRIC FIELD per unit charge AS THE CHARGE MOVES FROM ONE POINT TO THE OTHER.

More accurately, Electric Potential at a point is the Electric Potential Energy of a unit charge placed at that point, and the potential difference between two points is the difference between the Electric Potentials at the two points.

Also, if the answer is to be in Volts, the unit of electrical charge is the COULOMB, NOT the charge on the electron.

Ok. I admit you are more accurate braintic. But she asked for a simplified version.
So I simplified it assuming she has not done conservation of energy or work. You do that in module 3 of Preliminary.
