# What is electric current short answer?

Contents

Electric current is defined as the rate of flow of negative charges of the conductor. In other words, the continuous flow of electrons in an electric circuit is called an electric current. The conducting material consists a large number of free electrons which move from one atom to the other at random.

## What is electric current very short answer?

Electric current is basically the flow or charge of the electric charge in motion in a conductor. It is said to exist when there is a net flow of charge through the region. the current is given as the flow of charge per second: I=timecharge. The SI unit of current is Ampere.

## What is electric current?

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 current explain?

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 current and its types?

Current electricity is a constant flow of electrons. 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. In alternating current, electrons flow in both directions.

## What is current 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 mainly two different types of current: Direct current and alternating current.

## What is SI unit current?

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 ×1019 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆νCs.

## What is the best definition of current?

Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. … Electrons, the most common charge carriers, are negatively charged. They flow from relatively negative points to relatively positive points. Electric current can be either direct or alternating.

## How current is created?

When a metal wire is subjected to electric force applied on its opposite ends, these free electrons rush in the direction of the force, thus forming what we call an electric current.”

## 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.
