Electric Circuits Flashcards
1
Q
Potential difference
A
The work done per unit positive charge V=W/Q
2
Q
Current
A
The rate of flow of charge I=q/t
3
Q
Ohm’s law
A
Current through a conductor is directly proportional to the potential difference across the conductor at constant temperature.
4
Q
Resistance
A
A material’s opposition to the flow of electric current.
