Question 2

An engineer measures the potential difference across an electrical component and the current passing through it. Which calculation gives the electrical power dissipated by the component?

A

current+potential difference\text{current} + \text{potential difference}current+potential difference

B

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

C

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

D

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