asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode) and aheated cathode. Semiconductor diodes were the first semiconductor electronic devices. The discovery of crystals’ rectifying abilities was made by

terminal device with 3 junctions. When the anode terminal has positive voltage and no gate voltage is applied‚ the first and the third junction are forward biased and the second junction is turned reverse biased allowing no current flow through the thyristor. A thyristor starts to conduct when the voltage across the anode and cathode (VAK) is increased beyond the thyristors breakdown voltage (VBO). This is due to the avalanche breakdown that occurs in the second junction of the thyristor

The guitar dates back 4‚000 years. the oldest evidence of the the existence dates back to 1800 B.C. It was found in Babylonia on clay plaques. . A little later around the same time in Egypt had developed a necked instrument with marked frets wound around the neck. another was also found in a tomb and had deeper curves and was completely flat unlike older instruments that curved up to the sound board and two surfaces‚ back and front‚ were attached to each other with strips of wood that form the sides

Low-dropout regulator From Wikipedia‚ the free encyclopedia Schematic of a low-dropout regulator A low-dropout or LDO regulator is a DC linear voltage regulator which can operate with a very small input–output differentialvoltage.[1] The advantages of a low dropout voltage include a lower minimum operating voltage‚ higher efficiency operation and lower heat dissipation.[2] The main components are a power FET and a differential amplifier (error amplifier). One input of the differential amplifier

In this assignment‚ we are assign to construct a 2 button type Ac motor control system. The 2 type button means that there are only 2 buttons which is the stop button and the forward button. The successful build the whole system‚ a few component are very critical in this system. Circuit breaker First is the circuit breaker. Circuit breaker is a switch which is designed to prevent damaging the circuit when there is over load or short circuit. But the circuit breaker works differently compare
