What is the operating principle of LED? Working Principle: A light-emitting diode is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of […]

How many methods of coal analysis are there? two methods How do you know the grade of coal? The most common classification is based on rank, referring to the degree of coalification that has occurred.

A secondary function of a clarifier is the removal of floating matter (scum), which has accumulated on the water surface. What is the first step […]

What are the three 3 types of heat transfer mechanisms? The Three Mechanisms of Heat Transfer: Conduction, Convection, and Radiation. Is a sun conduction convection or radiation? Convection is the transfer of heat energy in a fluid. Air in the atmosphere acts as a fluid. The sun’s radiation strikes the ground, thus warming the rocks. […]
