## How do you describe 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.

## How do I calculate resistance?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

## What is resistance and its unit?

Siemens per meterElectrical conductivityOhm meterElectrical resistivityElectrical resistance/SI units

## What is resistance to change called?

Resistance to change is the action taken by individuals and groups when they perceive that a change that is occurring as a threat to them. Key words here are ‘perceive’ and ‘threat’. The threat need not be real or large for resistance to occur.

## 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 a specific resistance?

Specific resistance is defined as the resistance offered per unit length and unit cross-sectional area when a known amount of voltage is applied.

## What are the types of resistance?

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 resistance and types of resistance?

Resistance: The property of a substance which opposes the flow of electric current (or electricity) through it is called Resistance OR Resistance is the ability of a circuit which opposes current. Mica, Glass, Rubber, Wood etc. are the examples of resistive materials. The unit of resistance is OHM (Ω) where 1Ω = 1V/1A.

## What is resistance and how you can classify it?

When an electric current of one ampere passes through a component across which a potential difference (voltage) of one volt exists, then the resistance of that component is one ohm. (For more discussion of the relationship among current, resistance and voltage, see Ohm’s law.)

## How do I know what type of resistor I have?

Some resistors have contact plates on the bottom. Read the 3 or 4 numbers on the resistor. The first 2 or 3 represent the significant digits and the last indicates the number of 0s that should follow. For example, a resistor reading 1252 indicates a rating of 12,500 ohms or 1.25 kilo-ohms.

## What are types of electrical resistance?

The measuring unit of the electric resistance is the Ohm, The ohm is the resistance between two points of the conductor when the constant potential difference of 1 volt applied to these points, It produces the current of 1 ampere in the conductor, Types of electric resistance are the constant (fixed) resistance, and …

## Why resistance is used?

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 happens if resistance is too high?

A high resistance in the circuit means a very low current flowing in it when the voltage of the source is constant. … Low resistance in the circuit means a higher current is flowing in the circuit. It depletes the battery at a faster rate which means the battery can not last for a long time.

## What is the best type of resistor?

Between the three types of resistors based on composition, carbon-composition resistors, carbon-film resistors, and metal-film resistors, in overall performance, metal-film resistors are the best, carbon-film the next best, and carbon-composition resistors last.

## What are the two main 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 three types of resistance?

We call these three types of resistance: game change, outside game and inside game. This section will explain what makes each type of resistance effective, as well as how they complement one another.

## What is a sentence for resistance?

Examples of resistance in a Sentence Noun They have shown a stubborn resistance to change. The troops met heavy resistance as they approached the city.
