 # Question: What Is An Easy Definition For Resistance?

## What is resistance and its types?

Most types of resistor are linear devices that produce a voltage drop across themselves when an electrical current flows through them because they obey Ohm’s Law, and different values of resistance produces different values of current or voltage.

….

## How do I measure resistance?

Resistance is measured in ohms; 1 ohm is equal to 1 volt of electrical difference per 1 ampere of current (1 volt/1 amp). You’ll find your volt of electrical difference by taking several readings using your equipment. Resistance can be measured with an analog or digital multimeter or ohmmeter.

## What is the working of resistance?

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 are two types of resistance?

Resistors can be broadly of two types. Fixed Resistors and Variable Resistors.

## What are the factors of resistance?

Factors That Affect Resistance How much resistance a material has depends on several factors: the type of material, its width, its length, and its temperature. All materials have some resistance, but certain materials resist the flow of electric current more or less than other materials do.

## What is resistance and example?

Resistance is defined as a refusal to give in or to something that slows down or prevents something. An example of resistance is a child fighting against her kidnapper. An example of resistance is wind against the wings of a plane.

## What are the 2 types of resistors?

Basic distinction of resistor typesFixed resistors: Fixed resistors are by far the most widely used type of resistor. … Variable resistors: These resistors consist of a fixed resistor element and a slider which taps onto the main resistor element.

## 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 a symbol of resistance?

The ohm (symbol: Ω) is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm.

## What causes resistance?

An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.
