power switching device

The application of Boolean algebra to electronic devices such as computers, lies in the restriction of the variable to two possible condition 'On and Off' or 'True or False' or numerically '1 or 0'. The electric circuits carry out the Boolean logi..

Application to Switching Circuits - The application of Boolean algebra to electronic devices such as computers, lies in the restriction of the variable to two possible condition 'On and Off' or 'True or False' or numerically '1 or 0'. The electric circuits carry out the Boolean ..

'. 1 watt = Thus if a potential difference of 1 volt causes a current of 1 ampere to flow through a wire, the electric power consumed by the wire is 1 watt. The SI unit of electric power is watt (W). It is the power consumed by a device that carries 1 A of cu..

. Tidal mills were used for hundreds of years in some of the European countries. Schematic view of Turbines Fixed at the Bottom of a Reservoir The first small wave-energy device was built in Japan by Yoshio Masuda. Hundreds of navigation buoys use his system in the Sea of Japan. The Japan..

Summary - Machine is a device that is used to multiply force, or to gain speed, or to change the direction of a force, or transform energy. Levers, pulleys, inclined plane and gears are some of the examples of simple machine..

Electric Circuits and their Components - The devices which deliver electricity are called the 'sources'and lamps, electric engines, etc. which consume electricity are called 'loads'. Switches are used to switch the loads on and off whenever necessary. Hence, the source..

Question: Define watt and watt hour. Answer: Watt is the unit of power. If 1 joule of energy is consumed in 1 second, we say the power of the device is 1 watt. Watt hour is the unit of energy. If a device with a power 1 watt works for 1 h..

These modems, designed for portable computers, are the size of a credit card and fit into the PC Card slot on notebook and handheld computers. These modems are removed when the modem is not needed. Except for their size, PC Card modems are like a combination of external and internal modems. These h..

Domestic Electric Circuit - Electric power is usually generated at places which are far from the places where it is consumed. Distribution of Electricity from Grid The power is transmitted over long distances at high voltage to minimize the loss of energy during transmission. Fo..
