1
Q
What is resistance?
A
It is a measure of how easy or hard it is for charges to pass through a component in a circuit
2
Q
What is resistance measured in?
A
It is measured in the unit of ohms
3
Q
How is resistance calculated?
A
By measuring potential difference and current using the following equation:
resistance = potential difference (V) / current (A)
