An alternating current (AC) is an electric current whose direction reverses cyclically, as opposed to direct current, whose direction remains constant. The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy.

Would you expect to find an alternating or direct current in the secondary coil of a transformer?
An Alternating Voltage is induced in the secondary winding. When connected to an external load, you will have an alternating current.
What does ac stand for the mains voltage supplied in the UK?
AC stands for Alternating Current and DC stands for Direct Current.
Why cant you use a transformer to increase the voltage of a 60V solar panel?
The output of a solar panel is direct current. Transformers need alternating current to operate.
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.
Is it true that the current supply from electric power generating plants is an alternating current?
Yes, it is true that current supply from generating plants is an alternating current. There is no success found in bulk power generation of direct current ( D.C. ) in a power plant. But yes it is possible to transmit the power in the form of direct current ( High Voltage Direct Current Transmission-HVDC Transmission ) that possible after converting the generated alternating current into direct current with the help of high range converters.
What are the kinds of voltage?
Alternating current - AC, and direct current - DC.
What is term used when an Alternating current acts like a direct current?
The term is "rectification", which refers to the process of converting alternating current (AC) to direct current (DC). This is typically done using a rectifier circuit, which only allows current to flow in one direction.
Which apparatus changes a direct current to alternating current?
An inverter is the apparatus that changes direct current (DC) to alternating current (AC). It does this by converting the fixed voltage and direction of DC electricity into an oscillating voltage and alternating direction of AC electricity.
In electric terms what do the abbreviations AC and DC mean?
Its Alternate Current and Direct Current. I believe Angus Young got the idea for the band name when he say AC/DC on the bottom of his sisters sewing kit. Electric current can be direct current (DC) or alternating current (AC). Direct current such as the power from dry cells is characterized by a uniform direction of flow and amount (voltage) of electricity.
What is the meaning of DC Voltage?
D.C. stands for direct current. A.C. is alternating current.
Would you expect to find an alternating or direct current in the secondary coil of a transformer?
An Alternating Voltage is induced in the secondary winding. When connected to an external load, you will have an alternating current.
What is the Difference Between VAC and DC Current?
VAC is voltage of alternating current signalDC current is amperage of a direct current signalAnswerYour question contradicts itself, as the symbol, V,represents voltage, not current.However, V a.c., represents an alternating voltage -one in which the direction in which the voltage is acting continuously reverses itself. Vd.c. represents a direct voltage, in which the voltage continuously acts in the same direction.
What does ac stand for the mains voltage supplied in the UK?
AC stands for Alternating Current and DC stands for Direct Current.
How does ac dc power supplies work?
The mains to the house is an alternating current and this high voltage is stepped down using a transformer. The low voltage secondary alternating current is converted to direct current using 4 diodes wired as a bridge rectifier. The 'lumpy' direct current is smoothed using an electrolytic capacitor to smooth the resulting dc. It may need to be voltage regulated if the circuits it feeds are voltage sensitive.
What is rms value in ac system?
The r.m.s. value of an alternating current or voltage is the value of direct current or voltage which produces the same heating effect.
What is the difference between a transformer and a rectifer?
A transformer is used to change the value of a voltage applied to the transformer's primary winding to a different voltage value taken from the transformers secondary winding. A rectifier is used to change an alternating current value to a direct current value.
What type of current is used in your home alternating or direct?
In North America the electrical system is alternating current at a frequency of 60 Hertz. Europe and the UK use alternating current at a frequency of 50 Hertz. Direct current systems are obsolete because of the inability to transmit the voltage over long distances.
