# Quick Answer: What Are The Different Types Of Resistances And Their Purpose?

## What is called resistance?

Resistance is a measure of the opposition to current flow in an electrical circuit.

Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).

Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance..

## Where do we use resistors in everyday life?

Resistors are used for many purposes. A few examples include delimit electric current, voltage division, heat generation, matching and loading circuits, control gain, and fix time constants. They are commercially available with resistance values over a range of more than nine orders of magnitude.

## What is use transistor?

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.

## What are the 4 types of resistors?

The types of resistors include:Carbon Composition Resistor.Thermistor.Wire Wound Resistor.Metal Film Resistor.Carbon Film Resistor.Variable Resistor.Varistor﻿Light Dependent Resistor.

## What is resistor and their uses?

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

## What is 1m ohm?

We assume you are converting between megaohm and ohm. You can view more details on each measurement unit: megaohm or ohm The SI derived unit for electric resistance is the ohm. 1 megaohm is equal to 1000000 ohm. Note that rounding errors may occur, so always check the results.

## What does 2k7 resistor mean?

Resistor shorthand The letter R means multiply by 1. For example: 560R means 560. 2K7 means 2.7k = 2700.

## What are the color codes for resistors?

## What are different types of capacitors used for?

The types of capacitors available range from very small delicate trimming capacitors using in oscillator or radio circuits, up to large power metal-can type capacitors used in high voltage power correction and smoothing circuits.

## What are the two main types of resistors?

There are many types of resistors and they can be divided into two groups namely fixed resistor and adjustable resistor (variable resistor). The main function of the resistor is to resist the flow of electric current and regulate the flow of electrons. This is done by the material from which they are composed.

## What does R mean in resistors?

ResistanceEdit Resistance has a symbol of R measured in unit called Ohm which has a symbol Ω.
