What Is Resistor Made From

- March 13, 2019

These resistors are made from small rods of ceramic coated with metal such as a nickel alloy or a metal oxide such as tin oxide. The value of resistance is controlled firstly by the thickness of the coating layer.

Although copper wire is very low resistance there is still an element of resitance.

What is resistor made from. In these resistors a thin film of conductive though still resistive material is wrapped in a helix around and covered by an insulating material. The completed resistor was painted for color coding of its value. When the voltage reaches the part of the resistor that is a poor conductor the voltage is reduced or stepped down.

Other wire has higher resistance and high power resistors are often made from a coilf of wire. It has two terminals across which electricity must pass and it is designed to drop the voltage of the current as it flows from one terminal to the other. The center of the resistor is made from a material that is only a partial conductor of electricity like carbon.

The resistance is determined by the ratio of the fill material the powdered ceramic to the carbon. The general purpose of the resistor is to reduce the voltage of an electric current. A resistor is a component of a circuit that resists the flow of electrical current.

The thicker the layer the lower the value of resistance. A resistor is any material that exhibits a resistance. Most common modern resistors are made out of either a carbon metal or metal oxide film.

Most resistors use carbon to provide the resistive path. A resin holds the mixture together. Resistors can be constructed out of a variety of materials.

The resistive element is made from a mixture of finely powdered carbon and an insulating material usually ceramic.
