In the concept of electrical engineering and development, a switch is a device that has the functionality of connecting and disconnecting the conduction way in the electric circuit where it obstructs the current or redirecting it from one conductor to another conductor. The general type of switch is an electromechanical component that includes either one or more sets of mutable connected to outer circuits. The first implementation of the light switch was … [Read more...]
What is Bolometer : Circuit, Working & Its Applications
The initial development of the bolometer was done by Samuel Langley in the year 1878. Later on, in 1880, there were few modifications to the instrument in order to detect thermal radiation which holds the ability to thermally detect a wide range of spectrum including Fraunhofer lines. Then, Langley’s bolometer was used by Nikola Tesla for the application of power transmission in the year 1892. With this, the initial demonstration using a bolometer got … [Read more...]
What is Reluctance Motor : Construction & Its Working
The development of reluctance motor took place in the year 1838 so as to boost a locomotive. Here, the mechanical switches used for windings energization only hold the capability to provide energization for the motor at minimal speed levels. And in addition, electronic devices such as transistors, IGBTs are needed for driving the motors. But in 1920, the development of variable reluctance motor took place in the U.K and this development was used in many … [Read more...]
What is a Signal Generator : Types & Its Applications
The initial and commercial type of signal generator was invented in the year 1928 where it supports a frequency range of 500Hz - 1.5 MHz and in April 1929. The initial commercial frequency standard type signal generated was promoted by General Radio with a supporting frequency of 50 kHz. Coming to the first application of this device, an HP 200B audio kind oscillator was used for the calibration of Disney’s breakthrough stereo sound systems that were … [Read more...]

What is Flux Meter : Construction, Working & Its Uses
In the field of physics, particularly in electromagnetism, the concept of magnetic flux across the surface is defined as the surface integral of the general factor of the magnetic field which is represented with ФB. In order to measure the magnetic flux, there has to be a device, and it is the flux meter. Even though the development of flux meters started many years back, the usage of these devices started a few decades back. Now, with the advancement, … [Read more...]
What is Transformer Efficiency : Derivation & Affected Factors
We all know that transformer is the most crucial device in many electrical and electronic domains. This is considered as the passive device where the main purpose is to transfer electrical energy from one circuit to another or to many circuits. These are mainly implemented for increasing or decreasing the voltage levels in many applications. As we can state that device performance is noted by its efficiency, similarly transformer performance is known by … [Read more...]
What is Feedback Amplifier : Types & Its Applications
In the domain of electronics, a feedback amplifier is a component that acts in response to minimal voltage, power, and current signals and gives the output as a larger signal which comprises the crucial waveform characteristics of the input wave. These amplifiers exist in multiple forms which are extensively implemented in many electronic devices like televisions, computers, radio, and audio equipment. The functionality of amplification can be offered … [Read more...]
What is Anemometer : Types, Working Principle & Its Uses
The development of the anemometer happened in the year 15th century. In the year 1450, Leon Alberti was the person who developed the initial mechanical kind of anemometer. Later on, in the next centuries, many others along with Robert Hooke invented their own styles where few of them were wrongly acclaimed as inventors. Whereas during the period 1846, John Romney enhanced the initial version of it using mechanical wheels and hemispherical cups. Then, a … [Read more...]
