Drone In aviation and space, a drone refers to an unwritten plane or spacecraft. Another word for this is “unmanned aerial vehicle” or UAV. On Earth, drones are often used for military purposes because they do not endanger the life of the pilot. Apart from this, the drones don’t need Read more…
Graphene-based batteries are by and large effectively considered for an assortment of business applications. The enhanced execution and life cycle benefits when creating graphene-based batteries over traditional metal-particle batteries are definitely justified even despite the asset venture. Elon Musk’s Tesla Motors gives an outstanding case of inventive organizations effectively associated Read more…

Electronic color code How to read electronic color codes written on resistors The electronic code is employed to point the values or ratings of electronic elements, like resistors, capacitors, inductors, telecommunications cables et al..The electronic color code was developed in the early 1920s by the Radio Manufacturers Association (now part Read more…
Reading Capacitor codes Let’s learn about reading capacitor codes! Units of Capacitance: The base unit of capacitance is the farad (F). This value is very large for ordinary circuits, so smaller units have been made for measuring general purpose capacitors. 1 µf (microfarad) = 10-6 farads 1 nf (nanofarad) = 10-9 Read more…
