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 Carbon Composition Resistor : Construction & Its Working
The carbon composition resistor is the most fundamental and crucial electronic component which is extensively used in every circuit across electrical and electronic domains. There are various types of resistors that operate based on functionality, requirement, and design. They may range from minimal surface-mounted chip resistors to huge wire wounded power resistors. Even there exist various kinds of resistors which are constructed in multiple forms due … [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 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...]
What is Split Phase Induction Motor : Working & Its Applications
The development of induction motors took place by a French scientist named Francois. He was the person who formulated the presence of revolving magnetic fields which are called Arago’s rotations and this happened in the year 1824. Whereas during the period 1879, Walter Bailey exhibited the same principle through manually switching ON and OFF which is successfully called the initial primitive induction motor. And the first single-phase AC type of induction … [Read more...]
What is RGB LED : Schematic Diagram & Its Types
An LED is considered as the semiconductor light resource which produces light when there is current flow through the device. The color of the emitted light is known by the amount of energy needed for the electrons to traverse through the semiconductor’s bandgap. Initial LEDs were employed as indicator lamps in the place of incandescent bulbs. Whereas the modern advancements in LED have emitted high-level output appropriate for lighting in external … [Read more...]
