Electric Circuits Flashcards
1
Q
Potential difference
A
The work done per unit of positive charge/ voltage (V)
2
Q
Current
A
The rate of flow of charge / ampere (I)
3
Q
Resistance
A
A materials opposition to the rate of flow of electric current Ohm (Ω)
4
Q
emf (Electromagnetic field)
A
Total energy supplied per columb of charge by the cell (V)
5
Q
Ohm’s Law
A
Current through a conductor is directly proportional to the potential difference across the conductor at constant temperature.
