Quick Answer: What Are The Different Types Of Resistors?

Why do we use resistors?

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 the different types of resistances and their purpose?

Then to summarise, there are many different types of resistor available from low cost, large tolerance, general purpose carbon type resistors through to low tolerance, high cost, precision film resistors as well as high power, wirewound ceramic resistors.

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 4 types of resistors?

Different Types of Resistors – Fixed, Variable, Linear & Non-Linear Resistors & ApplicationsCarbon Composition Resistors.Wire wound Resistors.Thin Film Resistors.Carbon Film Resistors.Metal Film Resistors.Thick Film Resistors.Metal Oxide Resistors.Cermet Oxide Resistors (Network Resistors)More items…

What does R mean in resistors?

resistance of resistorI = current through resistor in amps (A) R = resistance of resistor in ohms ( ) V = voltage across resistor in volts (V)

What are the 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 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.

How do you tell the difference between resistors?

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 is MFR resistor?

Metal film resistors have a thin metal layer as resistive element on a non-conducting body. … Other film type resistors are carbon film and thick and thin film resistors. In most literature referrals to metal film, usually it is a cylindrical axial resistor.
