Electric Circuits Flashcards
1
Q
Potential Difference
A
The work done or energy transferred per unit charge to move the charge between two points in a circuit
2
Q
EMF
A
The energy provided by a battery per unit charge flowing through the battery
3
Q
Terminal potential difference
A
The voltage measured across the terminals of a battery when charges are flowing in the circuit
4
Q
Current Strength
A
The rate of flow of charge
5
Q
Resistance
A
The ratio of the potential difference across a component to the current in the component
6
Q
One ohm
A
Equal to one volt per ampere
7
Q
One coulomb
A
The charge transferred in a conductor in one second if the current is one ampere
8
Q
Ohm’s law
A
The potential difference across a conductor is directly proportional to the current in the conductor at a constant temperature
