Question

If $n$ is the number of electrons that flow through a conductor in time $t$, write down the expression for the current flowing through the circuit.

Answer 1

Step 1: Given Quantities:

$$\begin{gathered} chargeon1electron=e \\ chargeonnelectrons=ne \\ time=t \end{gathered}$$

Step 2: Formula Used:

$$\begin{gathered} I=\frac{q}{t} \\ I\to current \\ q\to charge \\ t\to time \end{gathered}$$

$I=\frac{ne}{t}$

Hence, the expression for the current flowing through the circuit is$\frac{ne}{t}$.
