DC voltage is a constant direction of current flow, it can be a constant amount or very (as long as it never changes direction it is DC). AC voltage is in the form of a sine wave (that will change direction of current flow) so at any specific instant of time you could measure a different voltage as it goes through its cycle.

∙ 13y agoUPS is uninterruptible power supply. Any UPS has a source of energy and is supplying a load. AC is alternating Current and DC is Direct Current.
If the device you are trying to power uses DC the source could be either batteries (DC), a generator that has an AC to DC converter, or perhaps a fuel cell of some sort. If your device uses AC it could have a DC battery backup, batteries being continually charged that is converted to AC via an inverter, or perhaps a generator that supplies AC directly.

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 in ac and dc powwer cable?
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
Why used ac over dc in train?
ac transmits the voltage over long distances. so v use ac in trains
What is the difference between alternators and dynamos?
Alternators produce AC, which is rectified by diodes if DC is needed. Dynamos produce DC by using a commutator.
What is the main difference between UPS and Inverter?
Inverter is the one which converts DC to AC. UPS is the one which provides you uninterrupted power supply. UPS as a system comprises of converter (converts AC to DC), battery, battery charger circuit and an inverter (converts DC to AC). Inverter is part of UPS.
What is the difference between AC and DC choke?
There is no difference between AC AND DC chockes
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 in ac and dc powwer cable?
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
What the difference between AC and DC?
AC rises with respect to time but DC is steady.
What is the difference between ac ammeter and dc ammeter?
dc ammeter has three connecting pins while ac has four
What is main difference between ac power and dc power?
AC power is made by alternating current and DC does not change.
Difference between magneto and ac generator?
magneto is dc
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 makes a dc bulb different from an ac bulb?
The voltage source that is applied to them is the difference between AC and DC light bulbs.
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
What is the difference between ac Hall effect and dc Hall effect?
ac hall effect always rises and dc is always in steady state.................
