What is electric current express it mathematically define its SI unit
Answers
Electric current -
The connection between voltage, current, and resistance is illustrated by Ohm's law. Ohm's laws declare that the current through any two points of the conductor is directly proportional to the potential difference applied over the conductor, given the physical conditions i.e. temperature, etc
SI Unit -
A system of physical units ( SI units ) based on the metre, kilogram, second, ampere, kelvin, candela, and mole, together with a set of prefixes to indicate multiplication or division by a power of ten.

An electric current is the rate of flow of electric charge past a point or region. 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
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 = V/R. ... Electric current generates an accompanying magnetic field, as in electromagnets.
simple electric circuit, where current is represented by the letter i. The relationship between the voltage (V), resistance (R), and current (I) is V=IR; this is known as Ohm's law.
