Question:-

What is Current ?

______________________

Answer:-

• the flow of electric charge is called electric current.
• In a quantitative way , we can say that the rate of flow of electric charge through any cross section of a conductor per unit time is called the electric current.
• the SI unit of electric current is ampere (A).
• It it is measured in the term of the rate of flow of charge.
• instrument used to measure electric current is called Ammeter.

$\sf{ \rm \red{electric \: current \: = \frac{charge}{time} }} \\ \\ \huge \underline{ \rm \red{or}} \\ \\ \ \\ \boxed{{I \: (ampere) = \frac{q(coulombs)}{t(second)} }{}}$
