In the year 1883, the inventor from America namely Charles Fritts developed a functional photoelectric cell. In the same year, Paul an engineer from Germany utilized the photocell in his observation called Nipkow’s disk. This is the instrument that takes images by measuring the object’s bright and dark locations and convert those into impulses in electrical form. The pre-invention of the modern-day photocell was developed by Hans and Elster by giving … [Read more...]

What is a Two Way Switch : Circuit & Its Working
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...]
