CHAPTER 1 : INTRODUCTION 1.1 Introduction Recently‚ we often hear cases of theft manhole made of steel. These thefts often occur because the steel is very valuable when sold. One of my neighbors asked if there are tools that can prevent theft drains. From there I got the idea to create an alarm that can prevent theft from stealing the drain cover becoming increasingly. We begin by examining the case drain theft either inside or outside the country. Too many cases that have occurred that resulted

Splices and joints are two names for essentially the same thing‚ that is‚ methods of connecting two pieces of wire so as to carry either a signal or an electrical current. Usually‚ these types of connections are achieved using a soldering iron. However‚ it is highly important that the splice or joint be strong regardless of whether solder has been applied or not. Several ways exist in which to accomplish this sort of a connection. Knotted tap joint A

The other processes‚ electric power transmission‚ electricity distribution‚ and electrical power storage and recovery using pumped storage methods are normally carried out by the electrical power industry. Electricity is most often generated at a power station by electromechanical generators‚ primarily driven by heat engines fueled by chemical combustion or nuclear fission but also

motor for an electrical appliance requires consideration of whether it will run at a set speed‚ how much power it must supply‚ whether it will be powered by AC or DC and what reliability is required. The essentials of an electric motor are the supply of electrical energy to a coil in a magnetic field causing it to rotate. The generation of electrical power requires relative motion between a magnetic field and a conductor. In a generator‚ mechanical energy is converted into electrical energy while

following: RESISTOR A resistor is a component of a circuit that resists the flow of electrical current. It has two terminals across which electricity must pass‚ and it is designed to drop the voltage of the current as it flows from one terminal to the other. Resistors are primarily used to create and maintain known safe currents within electrical components. Resistors are coated with paint or enamel‚ or covered in molded plastic to protect them. Because

if we chase perfection we can catch excellence!" -Vince Lombardi The five natural elements aside‚ the modern world today revolves around a sixth human developed energy i.e. Electricity. From telegraphy and telephony to electrical circuits for power‚ Electrical Engineering today focuses on a broad range of disciplines. The progress of this field has immensely influenced the advancement of technology. The vast application potential when combined with the notion of management intrigues me
