Define the unit of current.

1. The unit of current is Ampere.
2. Ampere is denoted as “A”.
3. One ampere measures the flow of electric charge across a surface at the rate of one coulomb per second.
4. 1 Ampere = One Columb (C)/One second (S).
5. Since the charge is measured in coulombs and time in seconds, so the unit is coulomb/Sec (C/s) or amperes (A).
6. Ampere is one of the SI base units for electric current. It is used in electronic and electrical science as well as other areas of science.
