INFORMATION OF RESIRTORS

 Introduction

Autis Boykin discovered the electric register, which obstructs the flow of electricity and emits electrical energy into the atmosphere in the form of heat. In electronic devices which require high heat heat, materials with higher resistance are used.

Resistors 1 (RESISTORS)

Every substance potentially opposes the flow of electric current because every action has a reaction). "When a piece of a material or a piece of wire made of it is converted into a part offering a certain resistance value, it is called a resistor." Resistors are also required in many types of electrical circuits. Like- Fan Regulator, D.C. The voltage regulator of the generator, the DC of the fluorescent tube. Circuit Neon Tester etc. This part controls the value of current flow in a circuit by introducing a resistance of the required value, which results in a drop in voltage.

It is used as a load, as a feedback element, to determine the value of the current flowing through a circuit and to reduce the value of the current flowing in it to discharge a charged capacitor after removing the input supply.

The property of matter in electricity that hinders the flow of electrons is called resistance. It is denoted by 52 (oha). Like- Mega Odha (10), Micro Odha (10 *).

  

1. Carbon Resistors - Carbon resistors are prepared by mixing a fine powder of carbon or graphite with a suitable dielectric and material. These are of two types.

(i) Fixed Value Resistors - To make fixed value resistors, a mixture made of carbon powder and bonding material is molded in the form of fine rods. Now the pieces are cut from the rod according to the required resistance value. A connecting wire is attached to each door with a metallic cap on either side. This connecting wire is a tin-coated copper wire, with a resistor in it. Resistors from Ochha to 20 MWh and are made in the wattage range of 0.125 cht to 2.

(11) Variable Value Resistor - To make Variable Value Resistors, the carbon powder and the prepared mixture are put in the form of Are Shaped Strip. This strip is tightly fixed on a suitable dielectric base. One connection is stressed at both ends. A moving arm is placed on top of the bar in such a way that its relationship remains with the middle connector. A variable resistance value can be obtained between the middle connector and either end connector. These resistors are made in the resistance range of 100 ohy to 5 mega ohtha and in the wattage range of 0.05 watt to 0.25 watt.

(2) Wire Wound Resistors -:Wire bound resistors are prepared by wrapping a fine and bare wire of an alloy called Eureka or Maganin on a pipe / sheet made of ceramic, ceramic or bakelite. Their current carrying capacity (wattage) is higher than that of carbon resistors. These are also of two types.

(i) Fixed Value Resistors-: Fixed value resistors are made in the wattage range of 0.1 oh to 50 kW and 1 watt to 50 watt one. Resistors in the range of wattage over 50 watts are also made for industrial use.

(ii) Variable Value Resistors - These variable value resistors are made by wrapping an alloy wire called Eureka or Magnin on a circular ceramic pipe. Like carbon variable resistors, they have moving arms and three connectors. They are generally made in the resistance range of 5 ohms to 5 kilo ohms and wattage to 50 watts.

Example- Rheostat- :Its structure is similar to that of a cylinder mounted on a stand. Its movable arm moves on a metallic rod. It is used to measure resistance in
