Why you say AC as alternating current not alternating voltage?
Because its the current that is alternatingAnother AnswerThere's absolutely nothing wrong with using the term 'alternating voltage', if you are describing voltage rather than current. However, In engineering terminology, the abbreviationa.c.is considered to be anadjective. So, it is also quite normal to talk about an 'a.c. voltage', in just the same way as we describe an 'a.c. system', or an 'a.c. motor', etc.
What is DC motor?
A DC motor is an electric motor that runs on direct current (DC) electricity. A DC motor is designed to run on DC electric power. Two examples of pure DC designs are Michael Faraday's homopolar motor (which is uncommon), and the ball bearing motor, which is (so far) a novelty. By far the most common DC motor types are the brushed and brushless types, which use internal and external commutation respectively to reverse the current in the windings in synchronism with rotation.
Does the alternating current supplied to the armature winding of a DC motor gets converted to dc by a commutator before it flows through the armature coil of the DC motor?
The commutator is a rotating switch, which reverse the polarity of the generated voltage every half-cycle. So it acts to rectify the output voltage.
Is the lightning is alternating or direct current?
i think it is ac. bcs the direction is changed with time. so it is ac
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.
Why is it incorret to say ac current?
The correct term is Alternating Current which AC stands for. So once you say AC you are saying Alternating Current. To say AC Current is to say Alternating Current Current.

What does kvac mean?
K = kilo = 1000's V = volts AC = alternating current So, 12 KVAC is 12,000 volts of alternating current

Why is it incorrect to say AC current?
ac stands for alternating current so ac current means alterneting current current. its like entering your pin number on an ATM machine.

What type of diode is used to convert alternating current into direct current?
The type of diode used to convert alternating current in to direct current is the power diode.
When a compass is placed near an electric outlet why does it move?
Electric current produce magnetic fields. However, in the case of AC (alternating current, usual in households), the current changes so quickly (and the current has an average value of zero) that I am not sure the effect on a compass would be visible to the naked eye.Electric current produce magnetic fields.

How do electrons flow on an ac source?
With electricity from the mains, the current chages direction 50 times each second, so it is called alternating current.
