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. High-power resistors that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements such as a volume control or a lamp dimmer , or as sensing devices for heat, light, humidity, force, or chemical activity.

In fact the resistor is probably the most common type of electronic component used in electrical and electronic circuits. There is a large number of different types of resistor that can be bought and used. The properties of these different resistors vary, and it helps to obtain the right type of resistor for any given design to ensure that the best performance is obtained. Although many resistors will work in a variety of applications the type of resistor can be important in some cases. Accordingly it is necessary to know about the different resistor types, and in which applications each type of resistor can be used.

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. Ohm is the measurement quantity of resistance, which produces one joule of energy in the form of heat in one second, when one ampere of current is flowing through it. The reciprocal of the resistance is called conductance. A resistor is a component or device designed to have a known value of resistance. Those components and devices which are specially designed to have a certain amount of resistance and used to oppose or limit the electric current flowing through it are called resistors.

A wirewound resistor is an electrical passive device that limits or restricts current flow in a circuit. Wirewound resistors are constructed using a conductive wire. The conductive wire is then wound around a non-conductive core. The conductive wire can be made of varying alloys and thickness to control the resistance value. Wirewound resistors are typically used in high power and industrial applications such as circuit breakers and fuses.

The resistor is a passive two terminal electrical components, that are used in most of the circuits. The resistors act as the lower voltage levels within the circuit and it is also used for reducing the current. The high power resistors can drive may watts of electrical power like heat. It is used for the motor controls in power distribution system. By using the temperature, time, and operating voltage can change the resistance of a fixed resistance. In the circuit elements the variable resistors are used in the form of light, sensing device to heat, chemical activity, and force.

There are many different types of resistor. Some are for special applications like being used as variable resistors, and others are used for surge limitation whilst.

[UPDATED] Explain The Different Types of RESISTORS pdf

The main function of a resistor within an electrical or electronic circuit is to oppose or resist the flow of current, hence named as resistor. A fixed resistor is one for which the value of its resistance is specified or fixed and cannot be varied in general. Their resistive element is manufactured from a mixture of finely ground carbon dust or graphite similar to pencil lead and a non-conducting ceramic clay powder to bind it all together. The ratio of carbon dust to ceramic i.
