## What is electric current in simple words?

An electric current is a flow of an electric charge between two points. … 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.

## Can the word current be used for electric current?

noun Electricity. the time rate of flow of electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit time: measured in amperes. Also called current, electricity.

## 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. In alternating current, electrons flow in both directions.

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

## 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 you mean by current?

Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. … The standard unit is the ampere, symbolized by A. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second.

## How current is generated?

When a voltage is applied to a conductor or semiconductor, electric current starts flowing. In conductors, positively charged protons are held in a fixed position and the negatively charged electrons move from one place to another place by carrying the charge. Thus, electrons conduct electric current in conductors.

## Why do we have 2 types of current?

There are two different types of current in widespread use today. … In a direct current, the electrons flow in one direction. Batteries create a direct current because the electrons always flow from the ‘negative’ side to the ‘positive’ side. In a direct current, the electrons travel in one direction.
