Resistance Flashcards
1
Q
What is resistance measured in?
A
ohms.
2
Q
What can resistance be calculated from?
A
The potential difference across a component and the current flowing through it.
3
Q
What is the total resistance of a series circuit?
A
The sum of the resistances of the components in the circuit.
4
Q
What is the equation to calculate the potential difference?
A
V = I × R
5
Q
How can the equation to find the potential difference be rearranged to find the resistance?
A
R = V ÷ I
