Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
How can you differentiate DC and ac?
DC is direct current. It is characterized as a voltage or current that is constant or, more precisely, always in one direction. A battery is an example of a DC source. AC is alternating current. It is characterized as a voltage or current that is alternating, i.e. changing direction at some frequency such as 50Hz or 60Hz. The power supplied to your home from the public power utility is an example of an AC source. ac is attractive in nature while dc is repulsive .
What kind of energy source does a transformer use?
Electrical (alternating current)
What measurement can vary with AC current by not DC current?
HZ. Hertz is the name given to the frequency of the alternating circuit. Direct current (DC) has no frequency since one wire is always positive and the other is always negative; but AC (Alternating Current) rapidly changes polarity, and does so at a rate that is defined by HZ.
What is the differences between direct circuit and alternating circuit?
Direct current and Alternating both are diffrent . Alternating current changes it's cycle 50 times in both direction in one second while the direct current doesn't change it's phase or frequecncy because it is free from frequency or frequency less(direct current).
What is a frequency of ac signal in Pakistan?
The current which changes it direction after every half cycle is called alternating current(A.C) or Alternating current which produced by voltage source whose polarity keeps on reversing with time. By Shahnam qadeer
What is Alternating current is measured in?
Alternating Current is measured in Amperes.
what is a frequency converter?
A frequency converter is a power electronic device. It transforms Direct current to Alternating current of desired frequency and magnitude.
High frequency is direct or indirect current?
-- There's no such thing as 'indirect' current.-- Direct current has no frequency. As soon as you mention 'frequency',you're talking about alternating current.
What is the difference between current (DC) and alternating current (AC)?
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
Do strobe lights use ac or dc current to flash?
Strobe lights use ac or alternating current to flash. The frequency of 50 Hz is alternating current's frequency, coming in handy for its flashing.
What is the purpose of a frequency converter?
A frequency converter converts "alternating current (AC) of one frequency to alternating current of another frequency." (Wikipedia) They are used to control the torque and speed of AC Motors. For more information go here: http://en.wikipedia.org/wiki/Frequency_changer.
What is the source of a alternating current?
A/c 60 cycles
What is frequency the current alternates in the US?
In the US AC current oscillates at 60 Hz.http://www.answers.com/alternating+current
Is transformer work without freqency?
No. A transformer has to have AC, alternating current, to work. And since it's alternating, it'll have a frequency.
What is the frequency of the alternating voltage and current typically used in the US?
60 Hertz
Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
