by Tarun Agarwal 5 years ago What is an Open Loop Control System & Its Working The first control system was invented by “James Watt’s Flyball governor” in the year 17. The main intention of this device is to maintain the engine speed constant by changing the steam supply to the engine. At present, the control...
by Tarun Agarwal 5 years ago What is Voltage Follower : Working & Its Applications Operational amplifiers are frequently used in a voltage follower design. But, this is not the finest arrangement in terms of potential risk & capacitive loading of oscillations. These loads have a huge impact on the op-amp stability...
by Tarun Agarwal 5 years ago Types of Losses in a Transformer and Their Efficiency An ideal transformer is very efficient so they don’t have energy losses, which means the power supplied to the transformer’s input terminal must be equivalent to the power supplied to the transformer’s output terminal. So the input...
by Tarun Agarwal 5 years ago What is an Anemometer : Working & Its Applications The first anemometer was developed in the year 1450 by Leon Battista Alberti. Several times, the design of this device was improved however there is no change in their basic principles. At present, there are different kinds of anemometers...
by Tarun Agarwal 5 years ago What is 7805 Voltage Regulator & Its Working For every electronic device, the regulated power supply is essential because these devices use semiconductor material with a fixed rate of voltage and current. If there is any difference in the fixed rate of voltage and current, then the...
by Tarun Agarwal 5 years ago What is Schering Bridge : Circuit, Working & Its Applications Schering Bridge is an electrical circuit used for measuring the insulating properties of an electrical cable and equipment. It is an AC bridge circuit developed by Harald Ernst Malmsten Schering (25th November 1880 – 10th April 1959)....
by Tarun Agarwal 5 years ago What is an Oil Circuit Breaker : Working & Its Types In the power system, an oil circuit breaker is an essential device because it will make the system strong. These are classified into different types based on the medium used to reduce the arc. An oil circuit breaker is one kind of circuit...
by Tarun Agarwal 5 years ago What is a Three Phase Inverter : Working & Its Applications An inverter is a power electronic device, used to change the power from one form to other like DC to AC at the necessary frequency & voltage o/p. The classification of this can be done based on the source of supply as well as related...
by Tarun Agarwal 5 years ago What is an Intermediate Switch & Its Working A switch is an electromechanical device that operates manually. It includes one or more electrical contacts and these are allied to exterior circuits. Every electrical contact includes two states namely closed and open. Closed is nothing...
by Tarun Agarwal 5 years ago What is Snell’s Law and Its Derivation Snell’s law depends on the law of refraction because it can predict the amount of bend of the light ray. The law of refraction is nothing but bending of a light ray when it is traveling between two different mediums like water or...
