Electric Circuits Flashcards
1
Q
Potential difference
A
The work done per unit positive test 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
***N.B. CONSTANT TEMPERATURE
4
Q
Resistance
A
A material’s opposition to the flow of electric current
5
Q
EMF
A
The total energy supplied per coulomb of charge by the cell
