Question

If Q units of charge flow through a conductor in the time ‘t’, such that ‘I’ is the current, then:

Options

• \[\text{I} = \frac{\text{Q}}{t}\]

• \[\text{I} = \frac{t}{\text{Q}}\]

• I = t × Q

• I = t + Q

Answer 1

\[\text{I} = \frac{\text{Q}}{t}\]

Explanation:

Current is charge divided by time

So \[\text{I} = \frac{\text{Q}}{t}\]

The other expressions either invert the ratio, multiply the quantities, or add them.
