Question

what is electric current. write it's formula and S.I unit​

Answer 1

Answer⤵️

Electric Current :-

☞ An electric current is a flow of electric charge in a circuit.

☞ More specifically, the electric current is the rate of charge flow past a given point in an electric circuit.

☞ The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes.

Formula :-

☞ 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.

SI Unit of Electric Current :-

Ampere A

All the best :)

Answer 2

Answer:

Electric Current:-

Electric current is defined as the rate of flow of electric charge. Or, electric current is the amount of charge flowing through a particular area in unit time and is given by: I = Q / t.

The S.I unit of electric current is Ampere (A).

Electric Current Formula:-

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.
