Understanding Fiber Optic Splicing and Data Losses

Optical fiber cable is the most important subject for large data and voice communication. Obviously like all other communication system, the primary objective of optical fiber communication system is to transfer successfully the signal containing information (voice, data, video) from the source to the destination without any or minimal data losses. Since the signals in… Read More: Understanding Fiber Optic Splicing and Data Losses »

What is Fiber Optic Cable Structure and Advantages

Fiber Optic cable is made up of thin fibers which are useful for the transmission of large amount of data. Infact the optical fiber is a hair thin cylindrical fiber of glass or any transparent dielectric medium. The fiber which are used for optical communication are wave guides made of transparent dielectrics. Its function is… Read More: What is Fiber Optic Cable Structure and Advantages »

Solar Cell Construction & Working Principle

Solar cell is a device or a structure that converts the solar energy i.e. the energy obtained from the sun, directly into the electrical energy. The basic principle behind the function of solar cell is based on photovoltaic effect. Solar cell is also termed as photo galvanic cell. The electricity supplied by the solar cell is… Read More: Solar Cell Construction & Working Principle »

photovoltaic effect & photoelectric effect – how solar panels work

This page explains how solar panels work, actually we shall understand what is photovoltaic effect that causes the light to convert in to the electricity or energy. In fact photovoltaic effect also called photoelectric effect is the effect that causes the production of solar electricity using the specific semiconductor materials. Before looking in depth the process of solar energy… Read More: photovoltaic effect & photoelectric effect – how solar panels work »

Alkaline Battery Evolution Construction & Usage

In new era, alkaline battery is one of the most important and most useful equipment. Normally battery is used where power supply is not regular and where low voltage is required (i.e. lower than supply voltage). Watches, mobiles and many other small equipment’s that require lesser voltage, mainly run on battery. The main advantage of battery is, they can be charged… Read More: Alkaline Battery Evolution Construction & Usage »

Working Principle of Battery

If we are willing to understand the basic principle of battery properly, first, we should have some basic concept of electrolytes and electron affinity. Actually, when two dissimilar metals or metallic compounds are immersed in an electrolyte, there will be a potential difference produced between these metals or metallic compounds. Hence causing the flow of current which is… Read More: Working Principle of Battery »
