What is Inductance?Inductance occurs when a change in current flow is exploited for the purpose of preventing signals with a higher frequency component from passing while allowing signals of lower frequency components to pass. This is why inductors are sometimes referred to as "chokes," since they effectively choke off higher frequencies. A common application of a choke is in a radio amplifier biasing circuit where the collector of a transistor needs to be supplied with a DC voltage without allo

With the development of Photoelectric effect, Crompton’s effect and Bohr’s model of atom, the idea of light or in fact radiations in general, being composed of particles or discrete Quanta was gaining wide popularity.However, the very established Huygen’s Principle and the results of Young’s double slit experiments made it very clear that light was wave and not a flow particles.The striking interference pattern observed by passing light through double slits was definitely a result of the wave na

What is the Schrodinger Equation?The Schrödinger equation (also known as Schrödinger’s wave equation) is a partial differential equation that describes the dynamics of quantum mechanical systems via the wave function. The trajectory, the positioning, and the energy of these systems can be retrieved by solving the Schrödinger equation.All of the information for a subatomic particle is encoded within a wave function. The wave function will satisfy and can be solved by using the Schrodinger equatio

Energy quanta are the smallest units of energy that can be transferred or exchanged in physical processes. They are the building blocks of quantum physics, which describes the behavior of matter and energy at the subatomic level. Energy quanta are also known as quanta, quantum, or energy packets.Quantum physics emerged in the early 20th century as a new branch of physics that challenged the classical physics of Newton and Maxwell. Classical physics could not explain some phenomena, such as the e

The unit of electrical resistance, the Ohm, is a cornerstone of the electrical world. Its importance in governing the behaviour of electric currents, designing efficient circuits, and ensuring the safe operation of devices cannot be overstated. By understanding the intricacies of resistance and Ohm's law, it is possible to harness the power of electricity to create innovative and practical solutions that benefit our daily lives.The world of electricity is complex and fascinating, with numerous c

The electrical light source which works on the principle of incandescent phenomenon is called Incandescent Lamp. In other words, the lamp working due to glowing of the filament caused by electric current through it, is called incandescent lamp.How do Incandescent Lamps Work?When an object is made hot, the atoms inside the object become thermally excited. If the object does not melt, the outer orbit electrons of the atoms jump to higher energy level due to the supplied energy. The electrons on th

o accurately calculate the voltage drop for a given cable size, length, and current, you need to accurately know the resistance of the type of cable you’re using. Voltage drop formulas can assist you to manually calculate voltage drop in cables that are under full load in branch circuits. It does not matter if you are working with copper oraluminum conductors.DC / single phase calculationThe voltage drop V in volts (V) is equal to the wire current I in amps (A) times 2 times one way wire size le

In 1958, E.G. Fridrich and E.H. Wiley had has developed Tungsten Halogen Lamp by introducing a halogen gas (basically Iodine) inside the incandescent lamp. Basically, without halogen gas, incandescent lamp filament gradually losses its performance because of its filament evaporation at higher temperature of operation. The evaporated tungsten from the filament of normal incandescent lamp gets deposited inside the bulb surface gradually. Thus lumens get obstructed from its way to come out from the

When working with individual capacitors in electronic circuits, it is essential to understand theirbehaviour and effects. For example, in a series arrangement, the positive plate of one capacitor is connected to the negative plate of the next capacitor in line. This unique connection impacts the circuit's total equivalent capacitance (C_total), causing the total capacitance to be smaller than the smallest individual capacitance (C) present in the series.A series circuit is characterized by its l

An electric lamp is a conventional light emitting component used in different circuits, mainly for lighting and indicating purposes. The construction of lamp is quite simple, it has one filament surrounding which, a transparent glass made spherical cover is provided. The filament of the lamp is mainly made of tungsten as it has high melting point temperature. A lamp emits light energy as the thin small tungsten filament of lamp glows without being melted, while current flows through it.Uses of E
