Resistance Flashcards
1
Q
What does the resistance of a component mean?
A
How easy or difficult it is an electric current to flow through it.
2
Q
What does the size of a current depend on?
A
It depends on the resistance of the circuit and on the voltage that is ‘pushing’ the current
3
Q
If the resistance stays the same what happens to the voltage and current?
A
The higher the voltage, the higher the current
4
Q
If the voltage stays the same what happens to the resistance and current?
A
The higher the resistance, the lower the current
5
Q
Do all metals conduct electricity?
A
Yes
6
Q
What does the resistance of a wire depend on?
A
The material from which it is made
Its length(longer wires have higher resistance)
Its thickness(thicker wires have lower resistance)
