Electric Current Formula

Electric Current Formula

Today, humans have instant electricity at the turn of a switch or a knob. Because of the electric current, this is possible. It is one of the significant discoveries that enabled us to completely alter how we live. Our lives depend entirely on electricity, from the moment we wake up until the moment we go to bed. Electricity is the continuation of the Electric Current Formula. The rate at which a conductor’s negative charges flow is referred to as the electric current. It implies that an electric current is the steady flow of electrons in an electric circuit. This article will go over the key ideas of an electrical circuit and the formula for electric current using examples. Let’s get to work learning!

A high number of free electrons that are randomly travelling from one atom to another make up the conducting substance. Free electrons that are not firmly attached will begin to move in the direction of the cell’s positive terminal when the potential difference is applied across a wire.

The electrical current is made possible by this constant flow of electrons. As a result, currents in the wire travel through the external circuit from the negative terminal to the positive terminal.

This conventional current flow has been in place for so long that it is still in use. Therefore, through the external circuit, electric current typically flows from the positive terminal of the cell to the negative terminal of the cell.

Electric Current Formula

The rate of electron flow is defined as the size of the current flow at any part of the conductor.

This can be modelled mathematically as:

I = Q/t


I Electric current

Q Electric Charge

T Time

The pace at which an electric charge changes within a circuit is known as the Electric Current Formula. The circuit’s voltage and resistance are related to this electric current. Ohm’s law can be represented as the following Electric Current Formula:

I= V/R


V Electric Voltage

R The resistance of the metallic wire

I Electric Current

The current formula was built on the Ohms law. The movement of electrons via an electric circuit is known as “current.” Potential differences cause the flow of electrons. The rate at which charges change over time is another name for current. I stands for current, and the SI unit of current is the ampere.

What is the Electric Current?

Electric current is the steady flow of electrons in an electric circuit. When the potential difference is provided across the wire or terminal, the electrons move. The pace at which an electric charge changes while travelling across a circuit is known as electric current. The voltage and resistance of a circuit are connected to this current. “I” can be used to express it, and the SI unit is an amp. Electric charge and time are related via the Electric Current Formula.

The Formula for Electric Current

The unit of electric current is the coulomb/Sec or ampere because students measure charge in coulombs and time in seconds. The SI unit for Electric Current Formula is the ampere. I represent electrical current. When the charge moves through an electric wire at a rate of one coulomb per second, the wire is said to carry a current of one ampere.

When responding to questions from the NCERT school textbooks, students who have access to the Electric Current Formula will benefit from having a solid understanding of both fundamental and advanced subjects. After finishing the chapter, students will have a solid conceptual comprehension of it. By comparing their responses to the  Electric Current Formula, they may evaluate their performance and make the required corrections.
