Electrical & Thermal Conductivity and Wiedemann Franz Law

Conductivity refers to the ability to conduct, convey or pass through, and in case of electricity it refers to ability to convey the electric current. On the other hand for thermal conductivity it is the ability to conduct or pass the heat for any material. Similarly if we talk about the reverse side of conductivity… Read More »

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 »

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 »

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 »

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 »
