Average Responding Voltmeter and Peak Responding Voltmeter: A simplified version of a circuit used in a typical average responding voltmeter is given in Fig. 4.23. The applied waveform is amplified in a high gain stabilized…
Average Power Formula: To find the average value of any power function, we have to take a particular time interval from t1 to t2; by integrating the function from t1 to t2 and dividing the…
Avalanche Photodiode - Definition, Basic Structure and Workings: The avalanche photodiode is similar to the P-N or PIN photodiode except that it is operated at high reverse-bias voltages so that impact ionization occurs, EHPs are…
Autotransformer | Definition | Use of Auto transformer: So far two-winding transformers have been discussed wherein the windings are electrically isolated. When the primary and secondary windings are electrically connected so that a part of…
Automation in Digital Instruments: Automation in Digital Instruments - One of the advantages of digital multimeters is their ease of operation. The reading is easy to take and does not lend itself to errors of…
Automatic Voltage Control: Automatic Voltage Control - Figure 8.20 gives the schematic diagram of an automatic voltage regulator of a generator. It basically consists of a main exciter which excites the alternator field to control…
Automatic Switch Circuit Breaker: The Automatic Switch Circuit Breaker is the simplest circuit interruption device is the knife switch. By closing the switch against the action of a spring we have an automatic device in…
Automatic Frequency Control Block Diagram: Automatic frequency control: As previously we see, the heart of an AFC circuit is a frequency-sensitive device, such as the phase discriminator, which produces a dc voltage whose amplitude and…
Automatic Combustion Control System: Automatic Combustion Control System is very popular nowadays and this has been developed mainly to maintain load against demand, to prevent smoke, to increase boiler house efficiencies, to carry out routine…
Automatic Bridge Circuit: The bridges discussed so far require that the controls be adjusted for balance after each capacitor (or other devices being tested) is connected to the bridge. In effect, they are manual. In…
