Electric current is a flow of electirc charges, in a particular direction.
Ampere is the SI unit of Electric current and it is denoted as '\(A\)'.
- Сoulomb (\(C\)) is the unit of electric charge.
- Ampere is a unit of electric current equal to a flow of one coulomb per second.
- The coulomb is defined as the quantity of electricity transported in one second by a current of one ampere.
- 'One ampere' is defined as one 'coulomb' of charge moving in a conductor in one second.
Ammeter is the device used to measure the electric current.
For example: When \(3\) coulombs of charge flow through a circuit for \(15\) seconds, calculate the current.
Given: Charge \(Q = 3 C\); time \(t = 15 s\)
