Hint: An electric current is the rate of flow of electric charge past a point or region.
Formula for electric current is $I = \dfrac{V}{R}$ where $V$ is the voltage supplied and $R$ is the resistance of the circuit.
Complete step by step answer:
An electric current is said to exist when there is a net flow of electric charge through a region. Electric charge is carried by charged particles, so an electric current is a flow of charged particles. The moving particles are called charge carriers, and in different conductors may be different types of particles. In electric circuits the charge carriers are often electrons moving through a wire. In an electrolyte the charge carriers are ions, and in an ionized gas (plasma) are ions and electrons.
The SI unit of current is ampere which measures the flow of electric charge across a surface at the rate of one coulomb per second. Since the charge is measured in coulombs and time in seconds, so the unit is coulomb/Sec (C/s) or ampere. Meanwhile, the formula for electric current is given as follows:
$I=\dfrac{V}{R}$
Where,
I = Electric Current
V = Voltage
R = Resistance of the material
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. The definition of ampere is based on the electromagnetic effect it induces.
Additional information:
In CGS system, there are two units of electric current, i.e. Electrostatic unit (esu) and Electromagnetic unit (emu).
Note: Current is usually denoted by the symbol $I$. Ohm’s law relates the current flowing through a conductor to the Voltage $V$ and Resistance $R$; that is $V=IR$.
An alternative statement of Ohm’s law is, $I=\dfrac{V}{R}$.
