in the day time. Having observed these problems being encountered‚ this project will be developed to bring about the automation of the switching of lighting system using light depending resistor (LDR). The project is an electronic switch that is controlled (turned on and off) by the amount of light shining on the LDR. When light strikes the LDR‚ the switch opens (turns off); when the LDR is in darkness‚ the switch

LIVE AND LET LIVE LIFE IS not as simple as it was before. With scientific and technological developments‚ man has become obsessive of luxurious lifestyle. Materialism has grasped all of us. It has made man insensitive to the human emotions of pity‚ compassion‚ generosity and affection. All of us want to prosper with material comforts and thus‚ we venture into the mad ‘rat race’. In this materialistic world‚ we are governed by our instinct rather than our by conscience. This is the modern era

Properties of Light Purpose: The ideal purpose of this lab activity is to investigate the relationship between the frequency of the light (color) and the energy produced by different colors of light. Other purposes of this experiment include calculating the proper current for each LED‚ measuring the evaporation rate of rubbing alcohol‚ and being able to discuss the outcome of the relationship in light energy and the color of the light producing the energy. Materials: Light Emitting Diodes

Light is just one portion of the various electromagnetic waves flying through space. The electromagnetic spectrum covers an extremely broad range‚ from radio waves with wavelengths of a meter or more‚ down to x-rays with wavelengths of less than a billionth of a meter. Optical radiation lies between radio waves and x-rays on the spectrum‚ exhibiting a unique mix of ray‚ wave‚ and quantum properties. At x-ray and shorter wavelengths‚ electromagnetic radiation tends to be quite particle like

What is light produced‚ reflected and refracted into visible light? Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The definition of produced visible light means when the electromagnets radiation meets the human eye. The first example of produced is a glow stick because it produces its own light . Another

HVDC LIGHT TECHNOLOGY ABSTRACT [pic] Transmitting power at high voltage and in DC form instead of AC is a new technology proven to be economic and simple in operation which is HVDC transmission. The HVDC (High Voltage Direct Current) technology is used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems. A further development in this technology is HVDC

ummary: Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Is there any person who comes to ON/OFF these lights? The following circuit that described below which perform this job automatically. This circuit employed the output from an uncomplicated light/dark activated circuit and oblige a relay in its output which can be further attached to switch ON/OFF a street light and electrical application in a household also.

Case Study – Ghost Stories Answer to Question 1 From the situation that Nils is going through‚ some available options are suggested as below: a. Nils should consult headquarter and ask for a number of construction workers from the main office or countries nearby to at least enable the project to be completed within the stipulated time frame. However‚ the administration along with the senior management might not agree‚ since staff for coordination and work purpose from abroad may incur excess
