The following points highlight the four main types of electrical quantities. The types are: 1. Electric Charge 2. Electric Current 3. Electromotive Force and Potential Difference 4. Electric Field Strength. Type # 1. Electric Charge: Electrical energy transfer occurs because of the action of electrical charges. Electric charge is an indication of the quantity of electricity and is usually denoted [...]
SI is the latest form of metric system and absorbs in it the rationalized MKSA system. SI stands for "Systeme International d' Unites" in French. This abbreviation is now adopted by the International Standardising Organisation as the abbreviated name of this new system of units in all languages. The SI system is, in fact, simply the RMKSA system expanded by [...]
In this article we will discuss about force, work, power and energy with their electrical units. Force: A force is that physical cause which when acting on a body changes or tends to change the state of rest or of uniform motion of the body in a straight line. The MKS or SI unit of force is the newton which [...]
