the proton. The intrinsic angular momentum (spin) of the electron is a half-integer value in units of ħ‚ which means that it is a fermion. The antiparticle of the electron is called the positron; it is identical to the electron except that it carries electrical and other charges of the opposite sign. When an electron collides with a positron‚ both particles may be totally annihilated‚ producing gamma ray photons. The concept of an indivisible quantity of electric charge was theorized to explain the chemical

the understanding of electrical circuits‚ spectroscopy‚ and the emission of black-body radiation. Kirchhoff formulated his famous circuit laws in 1845‚ while still a student at the University of Konigsberg‚ East Prussia. He completed this study as a seminar exercise‚ and it later became his doctoral dissertation. Kirchhoff’s Laws include two basic principles. Kirchhoff’s First Law‚ also called Kirchhoff’s Current Law (KCL)‚ states that at any node (junction) in an electrical circuit‚ the sum of

The history of telecommunication began with the use of smoke signals and drums in Africa‚ theAmericas and parts of Asia. In the 1790s the first fixed semaphore systems emerged in Europe; however it was not until the 1830s that electrical telecommunication systems started to appear. This article details the history of telecommunication and the individuals who helped make telecommunication systems what they are today. The history of telecommunication is an important part of the largerhistory of communication

The energy stored at the flashlight could either produce light or electrical for the phones to charge. We researchers have guessed that the energy that is stored in the flashlight has a capacity to charge a cellphone.

cross-sectional area of wires decreased. Resistivity of wires is a factor of affecting the resistance. Background information Electrical resistance Electrical resistance is a measure of the degree to which an object opposes the passage of an electric current. The SI unit of electrical resistance is the ohm.
