operated street lights are not switched off properly even the sunlight comes and also not switched on earlier before sunset. In sunny and rainy days‚ ON time and OFF time differ significantly which is one of the major disadvantage of using timer circuits or manual operation. This project exploits the working of a transistor in saturation region and cut-off region to switch ON and switch OFF the lights at appropriate time with the help of an electromagnetically operated switch

Magnetic effect of electric current is one of the major effects of electric current in use‚ without the applications of which we cannot have motors in the existing world. A current carrying conductor creates a magnetic field around it‚ which can be comprehended by using magnetic lines of force or magnetic field lines. The nature of the magnetic field lines around a straight current carrying conductor is concentric circles with centre at the axis of the conductor. The direction of the magnetic field

Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is

To build your circuit‚ you will need to know how to use a breadboard. Watch the video and see the Science Buddies reference How to Use a Breadboard. http://www.youtube.com/watch?v=6WReFkfrUIk 2. Now that you know how to use a breadboard‚ you are ready to assemble your BlueBot circuit. Table 2 shows a list of all the components in the circuit and where they go on the breadboard. You can download and print a PDF of this table—complete

solution of complicated networks (particularly‚ electronic networks) quite quick and easy. The Thevenin’s theorem‚ as applied to d.c. circuits‚ may be stated as under: The current flowing through a load resistance RL connected across any two terminals A and B of a linear‚ active bilateral network is given by VOC || (Ri + RL) where VOC is the open-circuit voltage (i.e. voltage across the two terminals when RL is removed) and Ri is the internal resistance of the network as viewed back into the

to be very dangerous if circuits are not properly protected. The major fault that appears in electrical network or equipment is termed as short circuit. In short circuit‚ the supply phase and neutral or earth is short circuited accidentally due to foreign metallic substance coming in contact with phase & neutral or earth or due to overload thereby damaging the insulation resulting in short circuit i.e. directly connected resulting in heavy current flow called "short circuit current". This high current
