Electrical Current Flashcards
1
Q
Define ‘Electrical Current’
A
- A current that keeps flowing in the same direction, which means that the charge moves in one direction only
2
Q
How can cells and batteries be used in electrical circuit?
A
- To supply direct current
3
Q
How does current flow?
A
- Through a component, but if there is a voltage across that component?
4
Q
Define ‘Voltage’
A
- The driving force that pushes the current round
5
Q
Define ‘Resistance’
A
- Anything in the circuit which slows the flow down
6
Q
What is ‘Resistance’ measured in?
A
- ohm
7
Q
In a circuit, what happens when the voltage is increased?
A
- More current will flow
8
Q
What will then happen in a circuit if the resistance is increased?
A
- Less current will flow
