Electricity and circuits background. When electrons flow against the opposition offered by resistance in the circuit friction occurs and heat is produced. Circuits can get much more complex consisting of dozens hundreds or even thousands or millions of separate components all connected with conductors in precisely orchestrated ways so that each component can do its bit to contribute to the overall purpose. For a more detailed discussion of direct and alternating current circuits see electricity. A circuit is a complete path around which electricity can flow.

An alternating current circuit carries current that pulsates back and forth many times each second as in most household circuits. A direct current circuit carries current that flows only in one direction. To most engineers the terms digital circuit digital system and logic are interchangeable in the context of digital circuits.

It must include a source of electricity such as a battery. Today s world of electronics has made deep inroads in several areas such as healthcare medical diagnosis automobiles industries. On a computer it is usually for the desktop while on a mobile phone it. A battery a lamp and an electrical wire that connects the two.

For example a very simple electrical circuit consists of three elements. Digital circuits are electric circuits based on a number of discrete voltage levels. Digital circuits are the most common physical representation of boolean algebra and are the basis of all digital computers. All have electronic components and devices.

Direct electric current and electricity. Electrical resistance measured in ohms is the measure of the amount of current repulsion in a circuit. Electric circuits are classified in several ways. Shortly after thomas edison invented his incandescent light bulb he sought practical applications for it by developing an entire power generation and distribution system the first such system in the united states was the pearl street station in downtown manhattan.

In this 21st century every day we are dealing with the electronic circuits and devices in some or the other forms because gadgets home appliances computers transport systems cell phones cameras tv etc. Materials that allow electric current to pass through them easily called conductors can be used to link the positive and negative ends of a battery creating a circuit.
