In the ancient period itself, the concept of good pump has discovered and moved on from that period, there were many progressions and changes that happened in the development of the pump’s design, construction, functioning, and others. The one kind of pump which we are going to discuss today is “Submersible Pump”. In the year 1916, Armais Sergeevich Arutunoff initially coined this pump, and the first usage was after the 1950’s only. Initially, these … [Read more...]

What is an Ohmmeter : Working Principle & Its Types
Initially, ohmmeters were evolved based on the design construction of a meter known as “Ratiometer”. Ohmmeters under this classification only calculate the value of resistance because they are not simply integrated into the multimeter construction. Insulation testers which depended on a hand moved generator also works on a similar operation. This makes sure that indication was completely autonomous of the developed voltage. Following this, various designs … [Read more...]
What is a Capacitor Bank : Working and Its Calculation
When a number of capacitors are connected together it forms a capacitor bank. They can be connected in series or parallel. A capacitor bank has numerous advantages and applications. Most of the time, these are used for reactive power compensation and power factor improvement. The arrangement of these can be done at substation or power plants. The unit for capacitance in Farads. A capacitor bank of lower scale is frequently used in industrial buildings, … [Read more...]
What is a Stepper Motor – Construction, Operating Principle & Uses
It is a type of motor used for precise movements and positioning of objects mainly in milling machines. It is a brushless type synchronous motor and it is operated stepwise. This step-wise rotation is considered as the step angle. One step angle is the rotation of the shaft per one step. The step angle can be of different degrees depending upon the construction of the rotor and stator teeth. The brushless motor rotates the shaft 360 degrees per one … [Read more...]
What is Resistivity and Its Variation with Temperature
Resistivity implies the measure of the resistance offered by an element for a given dimension at a particular temperature. Based on the resistivity, properties and characteristics of the element can be found out which are very important while designing a particular circuit, or applications. Even, based on its values, the element is categorized as conductor, insulator, or semiconductor. It need not be confined to only electrical property like the flow of … [Read more...]
What is an Inverter : Working Principle, Classification & Applications
An inverter is one of the most frequently used electronic circuits in most of the applications. It’s a circuit that converts fixed DC supply to alternating AC supply to feed AC loads. Widely used in commercial, aviation, residential and industrial applications. It could be regarded as the backbone for most of the applications. It is frequently used as an interfacing unit between DC supply and load. In many cases, it acts as an interfacing unit between AC … [Read more...]
What are Welding Types : Working and Their Applications
Well, we are no more in the bewilderment of how metals or thermoplastics are joined or attached, because we live in the era of extensively implementing various welding types. So, welding is one of the most prominent employment that was born several millions of years back. The only welding process that was in evolution until the 19th century was forge welding. The advancements in technology have shown multiple progressions in this welding and allowed us to … [Read more...]
What is an Ammeter : Working, Classification & Applications
An ammeter is a combination of words ampere and meter or we can say an instrument that measures ampere (current). Electrical quantities are to be continuously monitored being very dynamic. Real-time monitoring of current is of utmost importance as the current is the most flexible/dynamic electrical quantity. An Ammeter which facilitates monitoring of current is a basic instrument in electrical engineering. Approximately eighty percent of electrical … [Read more...]
What is Cascode Amplifier : Circuit, Working & Its Benefits
Well, We all know that the prominent usage of an amplifier is to amplify the signal strength whether the signal may be amplitude, frequency or other. So, the initial device which came into evolution to amplify the signal was the triode vacuum tube in the year 1906. The enhancements in digital electronics from the 20th century onwards offered modern approaches that are being added to the conventional amplifiers through digital switching so that … [Read more...]
What is Transistor Series Voltage Regulator : Working and Its Experiment
A regulator is a device that maintains constant and regulated power at the output terminals across the load. Due to voltage fluctuations, and load unbalancing, it becomes very important to maintain a constant voltage at the load side. The voltage fluctuations affect the function of the device, and hence the circuit. If the system consists of sensitive loads such as electronic devices, it becomes very important to maintain load voltage constant. Power … [Read more...]
