A - Currents In Electrical Circuits Flashcards
1
Q
What is a current?
A
The flow of electrical charge round the circuit. Current will only flow if there is a potential difference across that component
2
Q
What is potential difference?
A
The driving force that pushes the current round
3
Q
Potential difference is the same as ______
A
Voltage
4
Q
What is resistance?
A
Anything in the circuit which slows the flow down
5
Q
What does an ammeter do?
A
Measures the current in amps
6
Q
What does a voltmeter do?
A
Measures the potential difference
