The alternating current power line frequency of 60 Hz was the primary clock rate for the lowest level operations.

Atlas Autocode included a < code >< u > complex </ u ></ code > data type which would support complex numbers, partly because of pressure from the electrical engineering department, as complex numbers are used to represent the behavior of alternating current.

This type of meter responds to both direct and alternating currents ( as opposed to the moving coil ammeter, which works on direct current only ).

As alternating or direct current flows through the coil and induces a magnetic field in both vanes, the vanes repel each other and the moving vane deflects against the restoring force provided by fine helical springs.

This instrument can respond to both alternating and direct current and also indicated true RMS for AC.

For alternating currents, especially at higher frequencies, skin effect causes the current to spread unevenly across the conductor cross-section, with higher density near the surface, thus increasing the apparent resistance.

The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.

The electric charge flows in a constant direction, distinguishing it from alternating current ( AC ).

In alternating current ( AC, also ac ), the movement of electric charge periodically reverses direction.

Audio and radio signals carried on electrical wires are also examples of alternating current.

He fostered the development of alternating current that made possible the expansion of the electric power industry in the United States, formulating mathematical theories for engineers.

* Steinmetz,, " System of distribution by alternating current.

* Theory and calculation of alternating current phenomena ", with the assistance of Ernst J. Berg, 1897.

This unidirectional behavior is called rectification, and is used to convert alternating current to direct current, including extraction of modulation from radio signals in radio receivers — these diodes are forms of rectifiers.

Rectifiers are constructed from diodes, where they are used to convert alternating current ( AC ) electricity into direct current ( DC ).

When any wire ( or other conducting object such as an antenna ) conducts alternating current, electromagnetic radiation is propagated at the same frequency as the electric current.

In 1887, Nikola Tesla filed a number of patents related to a competing form of power distribution known as alternating current.

Central power stations became economically practical with the development of alternating current power transmission, using power transformers to transmit power at high voltage and with low loss.

In engineering or household applications, current is often described as being either direct current ( DC ) or alternating current ( AC ).

The time-averaged value of an alternating current is zero, but it delivers energy in first one direction, and then the reverse.

In summary, an AM signal consists of alternating positive and negative peaks of a radio carrier wave, whose amplitude or envelope is proportional to the original audio signal.

File: Tesla3. jpg | Nikola Tesla ( 1856-1943 ): developer of modern alternating current ( AC ) flow, improved on the dynamo, patents and theoretical work formed the basis of wireless communication and the radio, transformer and electric bulb and invented the Tesla coil.

Later known as the Fleming valve, it could be used as a rectifier of alternating current and as a radio wave detector.

Alternatively, the electrons can be accelerated by the oscillating electric field induced by an alternating magnetic field of a coil, which results in a self-sustaining discharge and omits any cathode ( radio frequency ion thruster ).

In communications and electronic engineering, a transmission line is a specialized cable designed to carry alternating current of radio frequency, that is, currents with a frequency high enough that their wave nature must be taken into account.

Radio frequency ( RF ) is a rate of oscillation in the range of about 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.

Electric currents that oscillate at radio frequencies have special properties not shared by direct current or alternating current of lower frequencies.

Audio and radio signals carried on electrical wires are also examples of alternating current.

In transmitting antennas, it is connected to the transmitter and converts the radio frequency alternating current from the transmitter to radio waves and feeds them to the rest of the antenna, which focuses them into a beam.

Nevertheless, the primary heating effect of all types of electromagnetic fields at both radio and microwave frequencies occurs via the dielectric heating effect, as polarized molecules are affected by a rapidly alternating electric field.
