Electric Circuits Flashcards
1
Q
Potential difference
A
The work done per unit positive charge
2
Q
Current
A
The rate of flow of charge
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 materials opposition to the flow of electric current
5
Q
Electrical power
A
Electrical,power dissipated in a device is equal to the product of the potential difference across the device and the current flowing through it
6
Q
emf
A
The total energy supplied per coulomb of charge by the cell
