EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

value determined by the lamp resistance and the value of the mains voltage at that instant in time. This transition generates Radio Frequency Interference. It is greatest when the triac is triggered at 90 degree and least when it is triggered at close to zero or 180 degree of the mains AC waveform. L-C suppression network is thus used to suppress these electrical noises. HISTORY : Light dimming is based on adjusting the voltage which gets to the lamp. Light dimming has been possible for many decades

V I will measure the Voltage and also Current of the wire. Once I have recorded the results I will repeat recording the results 2 more times at 2 more different voltages to make the experiment fair then I will find the average. I will record the Voltage and the Current of the wire in every 10 meters. I will record my results in a format of a table like this.

BASIC ELECTRICITY TEST TEST INFORMATION PAMPHLET WHY DO AT&T AND ITS AFFILIATES TEST? When individuals are being considered for our available job openings‚ they go through a selection process to measure their knowledge‚ skills and abilities to determine if they can perform the jobs in a satisfactory manner. It is to the advantage of both you‚ as a job candidate‚ and the company that only those who can perform at acceptable levels be placed on the job. Research has shown that tests provide accurate

factors. Some of these variables are listed below: Length of wire Diameter or thickness of wire Temperature at which wire is kept The material of which wire is made out of. The potential difference or voltage. Humidity Cross sectional area. Voltage across circuit All these factors will have to be kept constant except the diameter of the wire whilst doing the experiment to ensure that the investigation is a fair test. I have decided to investigate how the diameter
