Gray Code is one of the most important codes. It is a non-weighted code which belongs to a class of codes called minimum change codes. In this codes while traversing from one step to another step only one bit in the code group changes. In case of Gray Code two adjacent code numbers differs from… Read More: What is Grey Code?

Fluorescent light electronic ballast provides initial high voltage for discharging the gas inside the fluorescent lamps/bulbs. Ballast converts power frequency to very high frequency that initializes gas discharge process by controlling voltage and current through the lamps. There are different types of light ballasts which include electromagnetic, hybrid and electronics. On this page we are talking… Read More: Fluorescent Light Electronic Ballast Types Function Benefits & Specifications »
The electrical energy is almost exclusively generated, transmitted and distributed in the form of alternating current. Therefore, the question of power factor immediately comes into picture. Most of the loads (e.g. induction motors, arc lamps) are inductive in nature and hence have low lagging power factor. Low power factor is highly undesirable as it causes… Read More: Power Factor Improvement & Correction | Power Triangle & Capacitor… »
