How do resistors work?

A resistor works by restricting the flow of current, it can do this in one of three ways: firstly, by using a less conductive material, secondly by making the conductive material thinner and finally by making the conductive material longer.

What is resistor made up of?

Most common, modern resistors are made out of either a carbon, metal, or metal-oxide film. In these resistors, a thin film of conductive (though still resistive) material is wrapped in a helix around and covered by an insulating material. Surface-mount resistors are usually either thick or thin-film variety.

What is a resistor and its types?

A resistor is a passive component in a circuit which provides resistance to the flow of current. These resistors vary in their construction, power dissipation capacities, and tolerance to various parameters (such as temperature and light). The types of resistors include: Carbon Composition Resistor. Thermistor.

What can be used as a resistor?

All electrically conductive materials are somewhat resistive, too. Because of this, even a good electrical conductor, such as metal wire, can be used as a resistor. Resistance can be adjusted by limiting how thick the wire is, and by increasing or decreasing the conductive path through the wire.

What is a good example of a resistor?

Chapter 1 – Resistor Fundamentals Resistors are used for many purposes. A few examples include limiting electric current, voltage division, heat generation, matching and loading circuits, gain control, and setting time constants.

What does a resistor do simple?

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.
