The field of electronics comprises the study and use of systems that operate by controlling the flow of electrons (or other charge carriers,e.g. electron holes) in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is an integral technique in the field of electronics engineering and is equally important in hardware design for computer engineering. All applications of electronics involve the transmission of either information or power. Consumer electronics are electronic devices intended for consumer use. Consumer electronics usually find applications in entertainment, communications and office productivity. Consumer electronics are manufactured throughout the world, although there is a particularly high concentration of manufacturing activity in the Far East. One overriding characteristic of all consumer electronic products is the trend of ever-falling prices. This is driven by gains in manufacturing efficiency and automation, coupled with improvements in semiconductor design.

Nikola Tesla (10 July 1856 - 7 January 1943) was an inventor, electrical and mechanical engineer known for his patents and theoretical work that contributed to modern alternating current electric power (AC) systems, including the polyphase power distribution systems and the AC induction motor. His contribution was recognized and the derived SI unit measuring magnetic flux density or magnetic induction (commonly known as the magnetic field Lua error in package.lua at line 80: module 'Module:Box-header/colours' not found.

Motorola RAZR is a thin clamshell mobile/cellular camera phone from Motorola. The phone was initially regarded as an exclusive fashion phone, with a high price of $500 with service agreement and $800 without. However, in 2005 the phone entered the mass-market as a mid-priced phone. Motorola released a CDMA version of the RAZR on November 21, 2005, called the RAZR V3c. Changes in the CDMA version include a slightly thicker form factor, more internal memory (30 MB), and a higher resolution 1.3 megapixel camera.

The term was coined by Oliver Heaviside in February 1886. The SI unit of inductance is the henry (symbol: H), in honour of Joseph Henry. The symbol L is used for inductance, possibly in honour of the physicist Heinrich Lenz. The inductance has the following relationship: where; L is the inductance in henrys, i is the current in amperes, Φ is the magnetic flux in webers. Strictly speaking, the quantity just defined is called self-inductance, because the magnetic field is created solely by the conductor that carries the current. When a conductor is coiled upon itself N number of times around the same axis (forming a solenoid), the current required to produce a given amount of flux is reduced by a factor of N compared to a single turn of wire. Thus, the inductance of a coil of wire of N turns is given by: where,  |
