Electrical4U Before diving into the tuned collector oscillator, let’s understand what is an oscillator. An oscillator is an electronic circuit that generates an oscillating signal, like a sine or square wave. It converts a DC signal into an AC signal and is used in devices like TVs, clocks, radios, and computers. One of the simplest LC … Read more
Causes of Acidity in Insulating Oil In insulating oil in the transformer may occasionally come into contact with air. It may be during opening any blanking or due to leakage in the oil tanks or in associated pipe lines. Because of that the oxidation reaction in the transformer oil takes place, which further be accelerated … Read more
Superconducting materials have extraordinary properties that are crucial for modern technology. Research continues to explore and use these properties in various technological fields. Here are the key properties of superconductors: Zero Electric Resistance or Infinite Conductivity In a superconducting state, a material exhibits zero electric resistance (infinite conductivity). When cooled below its critical temperature, its … Read more
An operational amplifier, or op amp, is not only an amplifier; it can also perform a summing operation. This allows us to design a circuit that combines several input signals into a single output, creating a weighted sum of these inputs. Summing amplifier is basically an op amp circuit that can combine numbers of input … Read more
A Stirling Boiler is defined as a basic type of bent tube boiler commonly used in modern thermal power generating plants . It has one of the largest capacities among boilers, capable of generating up to 50,000 kg of steam per hour and producing pressure up to 60 kgf per cm². Designed by Alan Stirling … Read more
An operational amplifier or op amps is a linear device used for ideal DC amplification. It is fundamentally a voltage amplifying device that works with external feedback components like resistors or capacitors. An op amp has three terminals: inverting input, non-inverting input, and output. As you can see from the diagram, op amp has three … Read more
The world is slowly but continually moving towards a greener future. There is much excitement among engineers about the prospects of greener technology. However, coal-based power plants are still the primary source of electrical power in many countries. Baring few countries in the world like Norway or Iceland, all other countries depend heavily on coal … Read more
A Zener diode is defined as a specially designed diodes that works mainly in reverse bias conditions. These diodes are more heavily doped than ordinary ones, giving them a narrow depletion region. Unlike regular diodes that get damaged when the voltage exceeds the reverse breakdown voltage, Zener diodes function in this region. The depletion region … Read more
What is Discharging a Capacitor? Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges. We connect a charged capacitor with a capacitance of C farads in series with a resistor of resistance R ohms. We then short-circuit this series combination by closing the switch.As soon … Read more
A rotor is the rotating part of an electrical machine, where current is induced by a rotating magnetic field through transformer action. Induction motor rotor is of two types: Squirrel Cage Rotor In this type of rotor, the rotor winding consists of conductors, in form of copper or aluminum bars embedded in semi-closed slots of … Read more
