CHAPTER 1 INTRODUCTION INTRODUCTION 1.1 PROBLEM DEFINITION: The existing forms of security systems using surveillance cameras better known as CCTV are not enough. As they only provide the user with the video of any incident‚ which is of no use when it comes to stopping the incident from taking place if there is no one is present monitoring the screens at that point of time. This project will allow only the registered user to turn on the tracking system. This project will keep

gKit 32. TWO STAGE FM TRANSMITTER This Kit is a powerful two stage‚ 9V FM transmitter (Tx) with a range of up to 1 kilometer in the open. It uses an RF transistor in its output stage. Distance of transmission is critically dependent on the operating Conditions (in a building or out on the open)‚ type of aerial used (single wire or dipole)‚ operating voltage (12V is better than 6V) and if the circuit is peaked for maximum performance. The kit is constructed on a single-sided printed circuit board

Making Water Turbines Most Energy Efficient How does a wind turbine’s output vary with wind pressure (height of water)‚ the flow rate‚ size of the motor‚ and type of blade? Introduction There are many types of energy used today: Fossil fuels‚ coal‚ nuclear energy‚ solar energy‚ geothermal energy‚ hydrogen energy‚ hydroelectric energy‚ wind energy‚ and biofuels and biomass. Non-renewable energy sources such as fossil fuels and coal are diminishing since it cannot be recycled‚ unlike wind energy

Introduction: This project is one of the most famous electricity projects that can be performed successfully by most students in the age of 10 to 16. It helps students to learn about producing electrical energy using chemical energy. Since the same method is used to get energy from many fruits and chemicals‚ this project has many names. Following are some of the other names or titles for this project: |Fruit power or fruit battery

INTENSITY OF SUNLIGHT The Intensity of the sunlight is measured at different timings by using Lux Meter which measures the intensity of illumination. The Intensity of light is measured in Lux which is the S.I unit of measurement of intensity of illumination of a source. The results are tabulated in the Table 4 and plotted as shown in the Figure 7.

Purpose: The purpose of these experiments[1] was to measure the exciting current and determine the core losses in a transformer using the open circuit test (experiment # 2) and to determine the equivalent circuit of a transformer by using the short circuit method (experiment # 3). Introduction: In order to determine the equivalent circuit parameters of a transformer two simple tests are used‚ namely the open-circuit test (experiment #2) and the short-circuit test (experiment #3). By performing

Electrical Cable Cross section is just a two-dimensional view of a slice through an object. An often asked question: How can you convert the diameter of a round wire d to the circle cross section surface or the cross-section area A (slice plane) to the cable diameter d? Resistance varies inversely with the cross-sectional area of a wire. | ------------------------------------------------- Top of Form | Wire diameter d | unit | | | Cross-sectional area A | unit2 | | |
