Electric Circuits Flashcards
1
Q
Potential difference
A
Work done per unit of charge
2
Q
EMF
A
the total energy supplied per coulomb of charge by
the cell
3
Q
Current
A
Rate of flow of charge
4
Q
Resistance
A
The materials Opposition to the flow of electric current
5
Q
Ohms Law
A
Current through a conductor is directly proportional to the potential difference across the conductor at constant temperature
6
Q
Electrical power
A
The electrical power dissipated in a device is equal to the product of the potential difference across the device and the current flowing through the device.
7
Q
Kilowatt hours
A
It is a unit of energy, and 1 kWh is the amount of energy used when 1 kilowatt of energy is used for 1 hour.
8
Q
Internal resistance
A
The resistance inside a real battery.
