Question

What Is Current ? Write the formula & derivation of its formula.

Answer 1

Dear Student ,

Electrical current is a measure of the amount of electrical charge transferred per unit time. It represents the flow of electrons through a conductive material.

Current is a scalar quantity (though in circuit analysis, the direction of current is relevant).

The SI unit of electrical current is the ampere, defined as 1 coulomb/second.
Current formula is : I = Q/t or I = V/R .
By the use of Ohm's law you can easily derive the current .
