AC: Alternating Current

AC is an abbreviation of "Alternating current".

Alternating current (AC) is an electric current that once in a while reverses direction, in comparison to direct current (DC) which flows only in one direction. It is the form in which power of electric current is distributed to various businesses and a lot of residences, and it is the form of electrical energy that consumers and regular clients use in general, when they plug kitchen appliances, televisions, fans, and electric lamps into a wall socket. A widespread source of DC power is a battery cell in a flashlight. The abbreviations AC and DC are time and again used to signify alternating and direct current, as when they transform current or voltage.

• The standard waveform of alternating current in the majority of electric power circuits is a sine wave, whose positive half-period have a close similarity with the positive direction of the current and whose negative half-period have a close similarity with negative direction of the current.
• In some specific applications, like guitar amplifiers, a variety of waveforms are used, such as triangular or square waves.
• Audio and radio signals transmitted on electrical wires are also examples of alternating current. These categories of alternating current hold information such as sound (audio) or images (video) now and then transmitted by modulation of an AC carrier signal. These currents in general alternate at advanced frequencies in comparison to those used in the transmission of power.

AC Transmission and Distribution

• Electrical energy is used for the distribution of alternating current for the reason that AC voltage may be increased or decreased with a transformer.
• This process of energy transmission enables the power to be transmitted through power lines powerfully and proficiently at high voltage, which diminishes the energy lost in the form of heat due to resistance of the wire, and transformed to a lesser, safer, voltage for use. The use of a higher voltage leads to the considerably further proficient transmission of power.
• As an effect, power transmitted at a higher voltage needs a smaller amount of loss-producing current in comparison to that for a similar power at a lesser voltage.
• Power is frequently transmitted at hundreds of kilovolts, and transformed to 100 V – 240 V for domestic use.
• In a power plant, energy is produced at a suitable voltage according to the aim of a generator and then stepped up to a high voltage for transmission.
