In this article, you will study what are electric potential, the potential difference (PD) and electromotive force (emf) and the difference between them. Just as a body raised above the ground has gravitational potential energy, similarly, a charged body has electric potential energy. When a body is charged, work is done in charging the body. This work done is stored in the … [Read more...] about Electric Potential, Potential Difference and EMF

Stroboscopic Effect in Fluorescent Lamps
Fluorescent materials when subjected to electromagnetic radiations of particular wavelength, get excited and in turn, gives out radiations at some other wavelength. This is the working principle behind fluorescent lamps. These lamps are widely used in homes as they have higher efficiency and lifetime is almost 3 times of those of filament lamps. The Stroboscopic Effect in … [Read more...] about Stroboscopic Effect in Fluorescent Lamps
Series and Parallel Circuits – A Water Analogy
There are two basic ways in which to connect more than two circuit components - series and parallel. This video explains series and parallel circuits using water analogy. The analogy helps you to understand the concept easily. Some examples are solved in this video. Watch and share. … [Read more...] about Series and Parallel Circuits – A Water Analogy
MCB (Miniature Circuit Breakers) – Types, Working and Trip Curves
What is MCB? MCB or Miniature Circuit Breaker is an electromechanical device which protects an electric circuit from an overcurrent. The overcurrent in an electrical circuit may result from short circuit, overload or faulty design. In short, MCB is a device for overload and short circuit protection. They are used in residential & commercial areas. Just like we spend … [Read more...] about MCB (Miniature Circuit Breakers) – Types, Working and Trip Curves
