Electric Circuits Flashcards
Potential difference/voltage
Work done per unit of charge to move charge between 2 points
EMF
As the maximum energy provided by a battery per unit charge through it
Ohm law
The potential difference across a conductor is directly proportional to the current in the conductor at a constant temperature
EMF
As the maximum energy provided by a battery per unit charge passing through it
Power
As the rate at which work is done
Resistance
A measure of how much a conductor resists the flow of charge
Potential difference
Work done per unit of charge to move charge between 2 points
Electric charge
Indicates the humour of charged particles flowing
Unit of resistance
A conductor has a resistance of one ohm if a current of one ampere passes through it when a potential difference of one volt is maintained across it.
Short circuit
A path of very low resistance
Electric current
Flow of charge per unit time
