A resistor is a little package of resistance.

What is a resistor made of. The lead wires were wrapped around the ends of the resistance element rod and soldered. The resistive element is made from a mixture of finely powdered carbon and an insulating material usually ceramic. Normal resistor is a metallic alloy longer the wire higher the resistance.

The resistor is a passive electrical component to create resistance in the flow of electric current. It is is a fairly simple device. The thicker the layer the lower the value of resistance.

A wirewound resistor made with metal wire wrapped around clay plastic or fiberglass tubing offers resistance at higher power levels. Most common modern resistors are made out of either a carbon metal or metal oxide film. When the voltage reaches the part of the resistor that is a poor conductor the voltage is reduced or stepped down.

In these resistors a thin film of conductive though still resistive material is wrapped in a helix around and covered by an insulating material. In almost all electrical networks and electronic circuits they can be found. A resistor is any material that exhibits a resistance.

The thicker the layer the lower the value of resistance. Wire it into a circuit and you reduce the current by a precise amount. The general purpose of the resistor is to reduce the voltage of an electric current.

The completed resistor was painted for color coding of its value. Those used for applications that must withstand high temperatures are typically made of materials such as cermet a ceramic metal composite or tantalum a rare metal so that they can endure the heat. From the outside all resistors look more or less the same.

Resistors can be constructed out of a variety of materials. As you can see in the top photo on this page a resistor is a short worm like component with colored stripes on the side. An ohm is the resistance that occurs when a current of one ampere passes through a resistor with a one volt drop across its terminals.

Resistors are any thing that partially allow electric current. Resistors are made from small rods of ceramic coated with metal such as a nickel alloy or a metal oxide such as tin oxide. 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 by the thickness of the coating layer. In electronics carbon film threads are used as resistance. The center of the resistor is made from a material that is only a partial conductor of electricity like carbon.

Early 20th century carbon composition resistors had uninsulated bodies. 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.

Most resistors use carbon to provide the resistive path. Other wire has higher resistance and high power resistors are often made from a coilf of wire.
