Question

A charge of 20 C flows through a conductor in 4 s. The electric current through the conductor is:

Options

• 80 A

• 5 A

• 0.2 A

• 16 A

Answer 1

Using \[I = \frac{Q}{t}\], the current is \[I = \frac{20 \text{ C}}{4 \text{ s}} = 5 \text{ A}\]. The current equals the total charge divided by the time taken for it to flow.
