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.

He is considered to be the founder of quantum theory, and therefore one of the most important physicists of the twentieth century. In 1894 Planck turned his attention to the problem of black-body radiation. By interpolating between Wien's law and the Rayleigh-Jeans law, Planck found the famous Planck black-body radiation law, which described the experimentally observed black-body spectrum very well. The discovery of Planck's constant enabled him to define a new universal set of physical units (such as the Planck length and the Planck mass), all based on fundamental physical constants.

Devices in the iPod range are primarily music players, designed around a central scroll wheel. The full-sized model stores media on an internal hard drive, while the smaller iPod nano and iPod shuffle use flash memory. Like many digital audio players, iPods can also serve as external data storage devices. Lua error in package.lua at line 80: module 'Module:Box-header/colours' not found.  Ohm's law states that, in an electrical circuit, the current passing through a conductor, from one terminal point to another, is directly proportional to the potential difference (i.e. voltage drop or voltage) across the two terminal points and inversely proportional to the resistance of the conductor between the two terminal points. The SI unit of current is the ampere; that of potential difference is the volt; and that of resistance is the ohm, equal to one volt per ampere. In mathematical terms, this is written as:
where I is the current, V is the potential difference, and R is a constant called the resistance.  |
