Water Cooler Working Principle and Types: Water is one of the most needed thing for a person. In summer season cold water gives life to a thirsty person. At 10°C water is most refreshing. Thus…
Voltage Level Detectors: Voltage Level Detectors - Operational amplifiers are often used in circuits in which the output is switched between the positive and negative saturation voltages, +Vo(sat) and -+Vo(sat). The actual voltage change that occurs…
Digital Tachometer Working Principle: Digital Tachometer Working Principle technique employed in measuring the speed of a rotating shaft is similar to the technique used in a conventional frequency counter, except that the selection of the…
Explain Transistor Current Components: The various transistor current components which flow across the forward-biased emitter junction and reverse biased collector junction are indicated in Fig. 10.11. The current flowing into the emitter is referred to…
Q Meter: The overall efficiency of coils and capacitors intended for RF applications is best evaluated using the Q value. The Q Meter is used to measure some electrical properties of coils and capacitors. The…
Operating Modes of Pentium Processor: The Pentium processor architecture supports three Operating Modes of Pentium Processor such as protected mode, real-address mode and System Management Mode (SMM) and one 'quasi-operating mode' or virtual-8086 mode. In…
Explain Steady State Conditions in Semiconductor: Explain Steady State Conditions in Semiconductor - When the P-N junction is forward biased, current flows quite freely P to N in a P-N junction, as discussed in Fig.…
True RMS Voltmeter: True RMS Voltmeter - Complex waveform are most accurately measured with an rms voltmeter. This instrument produces a meter indication by sensing waveform heating power, which is proportional to the square of…
