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 '\(A\)'.
- Coulomb (\(C\)) 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.
Ammeter
For example:
When \(3\) coulombs of charge flow through a circuit for \(15\) seconds, calculate the current.
Given:
Charge \(Q = 3\ C\)
\( \)
Time \(t = 15\ s\)
