Current Flashcards
1
Q
What is current
A
The flow of electric charge measured in amps (A)
2
Q
What can electrical charge only flow round
A
A complete circuit, if there is a potential difference
3
Q
What is the current in a series circuit
A
The same everywhere
4
Q
What is potential difference
A
The driving force that pushes electric charge around a circuit, measured in volts (V)
5
Q
What is resistance
A
Anything in a circuit that reduces the flow of current, measured in ohms (Ω)
6
Q
The … the resistance across a component, the … the current that flows
A
Greater, smaller
