Question 4

Which of these equations is correct?

A

resistance=potential difference×current\text{resistance} = \text{potential difference} \times \text{current}resistance=potential difference×current

B

resistance=current÷potential difference\text{resistance} = \text{current} \div \text{potential difference}resistance=current÷potential difference

C

resistance=potential difference÷current\text{resistance} = \text{potential difference} \div \text{current}resistance=potential difference÷current

D

resistance=power×current\text{resistance} = \text{power} \times \text{current}resistance=power×current
