Electric current, **any movement of electric charge carriers**, such as subatomic charged particles (e.g., electrons having negative charge, protons having positive charge), ions (atoms that have lost or gained one or more electrons), or holes (electron deficiencies that may be thought of as positive particles).

## What is electric current in simple words?

An electric current is a flow of an electric charge between two points. Imagine it being like water in a river carrying energy. The electric charge in the electrons causes resistors in light bulbs and electric fires to heat up. It also creates magnetic fields in motors, inductors, and generators.

## What is the definition of electric current in physics?

An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.

## What is electric current with example?

Examples of current electricity are starting a car, turning on a light, cooking on an electric stove, watching TV, shaving with an electric razor, playing video games, using a phone, charging a cell phone and more.

## What is electric current and its formula?

The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).

## What are types of current?

There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current.

## What is meant by 1 ohm?

One ohm is equal to the resistance of a conductor through which a current of one ampere flows when a potential difference of one volt is applied to it.

## What is called current?

Current is the rate at which electrons flow past a point in a complete electrical circuit. At its most basic, current = flow. It expresses the quantity of electrons (sometimes called “electrical charge”) flowing past a point in a circuit over a given time.

## What is SI unit current?

Unit of electric current: ampere (A) The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 ×10^{−}^{19} when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆ν_{Cs}.

## What is an example of current?

The definition of current is something that is happening now or something that is up to date. An example of current is today’s newspaper. Passing from one to another; circulating. Current bills and coins.

## What is electricity formula?

Electrical energy is the product of power multiplied by the length of time it was consumed. In other words, Energy = power x time and Power = voltage x current. Therefore electrical power is related to energy and the unit given for electrical energy is the watt-seconds or joules.

## How does current work?

A current of electricity is a steady flow of electrons. When electrons move from one place to another, round a circuit, they carry electrical energy from place to place like marching ants carrying leaves. Instead of carrying leaves, electrons carry a tiny amount of electric charge. 3

## What is Ohm’s law state?

Ohm’s law states that the current through a conductor is proportional to the voltage across the conductor. V=IR where V is the voltage across the conductor and I is the current flowing through it.

## What’s the formula of current?

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.

## What is electric current explain with diagram?

An electric current is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge. If the electric charge flows through a conductor, we say that there is an electric current in the conductor. In the circuits using metallic wires, electrons constitute a flow of charges.
