Electric Discharge LampsA lighting device consisting of a transparent container within which a gas is energized by applying an electric voltage and thereby made to glow is known as electric discharge lamp. The electric discharge lamp is also known as vapor lamp or gas-discharge lamp.Actually, the electric discharge lamp is family of artificial light sources that generates light by sending an electric discharge through an ionized gas. In all types of electric discharge lamps, an electric current is passed through a gas or vapor which renders it luminous. The most commonly used elements in these types of lamps are neon, ...

LED BulbLED stands for Light Emitting Diode. The LED bulb has a P-N junction diode which produces light when an electric current passes through it. In LED bulb, when forward bias is applied to the PN junction, the recombination of charge carriers takes place. The result of this recombination of charge carriers is the emission of light and heat.CFL BulbCFL stands for Compact Fluorescent Lamp. The CFL lamps emits light by the ionization of mercury vapors. In CFL, the ionized low pressure mercury vapors produce UV rays, these UV rays collide with the phosphor coating and hence visible light is ... Read More
Incandescent BulbIncandescent bulb is a type of filament lamp which produces light by heating a filament made up of metals. The incandescent bulb operates on the principle of incandescence, which is the emission of light by heating metal filament.Incandescent lamps were the first type of electric illumination and invented by Thomas Alva Edison, an American inventor.An incandescent lamp is generally made out of a glass shell that houses a tungsten filament. An electric current flowing through the filament, heating it up to the temperature enough to produce light.Fluorescent LampA fluorescent lamp is a type of gas-discharge lamp which uses electric ...

In this article, we will compare and contrast the various features of different types of light sources such as incandescent lamps, fluorescent lamps, sodium vapor lamps and mercury vapor lamps.Starting and StoppingIncandescent lamps have instantaneous start and they become momentarily off when the power supply cuts off.Fluorescent lamps have a reaction time of one second or a little more at the start. These lamps go off and restart when the power supply is restored.Sodium vapor lamps have a starting time of 5 to 8 minutes. These lamps turn off, when the supply goes off and cannot be restarted after the ... Read More
Arc WeldingA welding process in which an electric arc is used to produce heat to melt and join the metals is known as arc welding. In the arc welding, an AC or DC welding power supply is used to create the electric arc between a consumable or non-consumable electrode and the base material.Laser WeldingThe welding process in which a laser beam is used as the source of energy to melt the materials being joined is known as laser welding. It is a high energy density beam process, and can be used to join thick materials with deep and narrow weld.Hybrid ... Read More
What is Electrolysis?The process in which ionic substances are decomposed into simple substances by passing an electric current through them is known as electrolysis.In other words, the process based on the fact that electrical energy can produce chemical changes is known as electrolysis.Applications of ElectrolysisNowadays the electrolytic process is widely used in various industrial applications. The major applications of the electrolysis are given below.Extraction of Metal from their OresThe electrolytic process is used for extracting out the pure metal from their ores, this process is known as electro-extraction. In the electro-extraction, the metal ore is treated with strong acid or ... Read More
Light is the natural agent that simulates sight and makes the things visible. Light is also known as visible electromagnetic radiation as it is capable of causing a visual sensation and its wavelength varies from 380 nanometers to 780 nanometers.Characteristics of LightThe main characteristics of light are given as follows −Light is nothing but a form of energy produced by a luminous object.It is an electromagnetic radiation, thus it can travel through vacuum.In an optically homogeneous medium, light travels in a straight line.When light falls on a polished surface such as mirror or metal surface, it bounces back. This bouncing ... Read More
In Golang, we can use the binary operators "&" (AND) and "|" (OR) to convert strings from lowercase to uppercase and vice versa. Let's take a simple example and understand how to use these binary operators in Golang. Examplepackage main import "fmt" func main(){ fmt.Printf("Lowercase characters using OR operator: ") for ch:='A'; ch
Duration of FundsThe main difference between closed-ended and open-ended mutual funds is that the closed-ended funds are for a specific duration, while the open-ended funds have no specific duration.The investors in open-ended funds may join and leave the funds anytime they wish.In case of closed-ended funds, the investors must stay invested for a specific duration pre-set by the fund managers.Number of Outstanding SharesIn case of closed-ended funds, there is a fixed number of shares outstanding which are traded in the market. The markets may include the share markets or OTC (Over the Counter) markets. The price of the shares is ... Read More
There are many similarities between bonus shares and share splits.In both the cases, the total number of outstanding shares goes up.Share split and bonus shares both increase the good future outlook of the shares.A company issuing a bonus share or splitting its shares shows a kind of promise to the shareholders that the future of the company is healthy and there would be no issues with profitability in the future.However, there are differences in the way the bonus shares and the share splits are treated in accounting.In case of bonus shares, the reserves and surplus capital goes down due to ...
