Code: GE6162 Lab Name: Engineering practice 4 P a g e EX. NO.1 STUDY OF ELECTRONIC COMPONENTS AND EQUIPMENTS AIM: To study about the following electronic components and equipment. Resistor color coding (ii).
Usage of CRO (Cathode Ray Oscilloscope) and Multimeter THEORY: ELECTRONICS: It is the branch of science, which relates to the conduction of electricity through a) vacuum, b) gases and c) semiconductors. The electronic devices are fairly complex, they are made of simple components such as: Resistors, Capacitors, inductors, tube devices and semi-conductor devices. Resistors, capacitors and inductors come under passive components and tube devices and semi-conductor devices fall under active components. PASSIVE COMPONENTS RESISTORS: It is a passive electronic component, which exhibits the property of the ‘resistance’. Resistance is a physical property of the material, which opposes the flow of current. Resistors are used in circuits to limit the flow of current or to provide a voltage drop. UNIT: • Department of ECE Sub.
Code: GE6162 Lab Name: Engineering practice 5 P a g e Ohms ( ) SYMBOL: TYPES Resistors are broadly classified in to two categories as 1) Fixed Resistors 2) Variable Resistors Fixed Resistors: Fixed resistors are those whose values cannot be changed after manufacturing. Variable Resistors: Variable resistors are those whose values can be changed after manufacturing. (i) RESISTOR COLOUR CODING Resistance is coded to indicate the value and the Tolerance. For axial type resistors, four color bands are used as shown in figure. The first three color bands indicate the resistance value and the fourth one indicates the tolerance. The first colour band gives the first significant digit and second colour band gives the second significant digit. Black Max Service Manual.
Third colour band is the multiplier and 2.2k RESISTOR • Department of ECE Sub.

Code: GE6162 Lab Name: Engineering practice 7 P a g e CAPACITORS: A capacitor is a component that stores electric energy. It consists of two conducting plates, separated by an insulator.
The conducting surfaces are called electrodes and the insulating medium is called dielectric. UNIT: Farads SYMBOL: TYPES: In general capacitors are classified as Fixed Capacitors Variable Capacitors Fixed Capacitors: Fixed Capacitors are classified into several types depending upon the dielectric material used. Some of them are Paper Capacitors Film Capacitors Mica Capacitors Glass Capacitors Ceramic Capacitors Tantalum Capacitors • Department of ECE Sub. Code: GE6162 Lab Name: Engineering practice 8 P a g e Variable Capacitors: Variable capacitors consist of a set of fixed plates and a set of movable plates with air as dielectric. The change of capacitance is obtained by changing the position of the moving plates with respect to fixed plates. Trimmer Capacitors Ceramic trimmer Capacitors Mica trimming Capacitors INDUCTORS: Inductor is a component whose construction is simply a coil of wire.
