Electric potential difference Flashcards
1
Q
What is the potential difference V between two points?
A
Work done per unit charge to move a point charge from one point to another
Work done is the same no matter what path is followed
2
Q
Formula for potential difference V
A
V=W/q
3
Q
Electronvolt
A
Work done when one electron charge is taken across a potential difference of one volt
4
Q

A
2eV
6
Q
3electron charges move across 5V, W=?
A
15eV
