Best Answer

VAC is voltage of alternating current signal

DC current is amperage of a direct current signal

Answer

Your 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 is the difference between ac and dc grounding?

The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.


What is the difference between 24VAC and DC 24V1.0A output?

I can say that 24VAC means 24 volts alternating current. 24VDC @ 1A means 24 volts direct current delivered at 1 ampere. So the difference I suppose would be: 1. Alternating current VS. Direct current 2. X Amperes(VAC) VS. 1 Ampere (VDC)


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.


What is main difference between ac power and dc power?

AC power is made by alternating current and DC does not change.


What is the difference between elecrical and electronics?

in electronics we use DC current but in elctrical equipment we use AC current


Difference between AC and DC generator?

The major difference between an AC generator and a DC generatoris that the DC generator requires a mechanism to provide a DC output. This can be done mechanically with a commutator or electronically with a rectifier. Internally, all generators produce an alternating voltage. Allgeneratorsrequire a magnetic field.


What is DC in electric stand for?

Volts direct current eg battery As opossd to Vac wich is volts altinating current eg mains supply


What is the difference when selecting a cable between AC and DC current?

AC. is alternating current and Dc is direct current. alternating equivalant to pulsating electricity while direct is a constant draw with little fluxuation.


What is the difference between ac voltage and dc voltage?

access current ( like plugs in your house ) direct current (like batteries)


Is their any other difference between ac and dc current?

Yes, there is. AC = Alternating Current, the direction of the current alternates, thus the name. DC = Direct Current. Things like computers need DC (they use a AC to DC converter inside the power supply to convert it) Hope that helps a bit.


What is the difference between AC and DC choke?

There is no difference between AC AND DC chockes


What is the difference between an ac drive and a dc drive?

The differenece is in the type of current it uses. AC is usually what is used in the home and DC from something like the car battery.
