Question

Name and define the SI unit of current.

Answer 1

Current:

1. Electric current can be defined as the flow of charge particles like electrons or ions. It is measured as the net flow of electric charge per unit of time.
2. Mathematically current is expressed as $I=\frac{q}{t}$, where $q$ is charge and $t$ is time.
3. The SI unit of current is ampere.
4. Ampere is defined as the rate of electron flow through a conductor.
5. $1ampere$ of current represents $1coulomb$ of charge flowing in $1second$.
