Question:

Define current.

Electric Current

Electric current is the flow of charges. It is measured as the number of charges crosses at a given point in unit time. The unit of current is Ampere.

Answer and Explanation:

The current is the number of charges passing through a material or a point in unit time. It is expressed in Amperes.

Mathematically we can write the electric current as,

{eq}\displaystyle I=\frac{q}{t} {/eq}

Where

  • {eq}I {/eq} is the current,
  • {eq}q {/eq} is the charge and
  • {eq}t {/eq} is the time.
