Resistor Basics Pdf

4 composition resistor the interior of a wirewound resistor consists of a ceramic or.

Resistor basics pdf. Different types of resistors resistors are the most fundamental and commonly used component in all the electronic circuits. The resistor value is read from the left to right. If there is no tolerance band then find the side that has. The units of resistance is ohms which is indicated by ω omega.

The symbol for a resistor is as shown below. Whether it is a carbon resistor or a metal film resistor all resistors with a fixed resistance are represented by this symbol. The symbol of the fixed resistor in the circuit diagram represents the resistor body with a long square and the short lines on both sides respectively indicate the two lead out lines of the resistor. R 1 134700 470ω resistor 0 25w r 1 141000 1kω resistor 0 25w r 1 143300 3 3kω resistor 0 25w r 1 151000 10kω resistor 0 25w.

Introduction to basic components 4 experiment 1. Basic electronics resistors resist is the word which means â to opposeâ. Resistors are usually added to circuits where they complement active components like op amps microcontrollers and other. Resistor color code guide 2 0 x10 000 10 20 x 10 000 200 000 1 000 1k resistor 200 k with a 10 tolerance first band second band multiplier band tolerance band equation the gold or silver band is always placed to the right.

This is one of the basic components used in emergency lighting medical devices battery operated equipment and many more applications. They are passive components meaning they only consume power and can t generate it. Resistors are nothing but hurdles and obstructions in the path. 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.

Semiconductors are tremendously important technologically and 1 diodes are really not used in digital circuits. 11 nov 08 application note vishay beyschlag application note fig. The word resistor came from the property of resistance which means to oppose current. Basic semiconductor physics 4 2 6 a semiconductor is a solid whose electrical conductivity is in between that of a metal and that of an insulator and can be controlled over a wide range either permanently or dynamically.
