Electric Circuits Flashcards
1
Q
potential difference
A
the work done per positive unit charge
indicates energy difference
2
Q
current
A
the rate of flow of charge
3
Q
current strength
A
the amount of charge which flows past any cross section in a conductor, in one second
4
Q
Ohm’s Law
A
Current through a conductor is directly proportional to the potential difference across the conductor at a constant temperature
5
Q
resistance
A
a material’s opposition to the flow of charge
6
Q
Emf
A
the total energy supplied per couloumb charge by the cell
