DC voltage refers to "direct current," and it can mostly be found in batteries. It means that it flows constantly through the circuit, as opposed to AC (alternating current) which switches flow quickly. There are benefits and downsides to direct current, the benefits being that it is best suited for low-current applications and is easy to work with, the downside being that it loses energy quickly as it flows and cannot reach very high power (voltage).
AnswerIn this context, 'd.c.' is being used as an adjective to describe the nature of the voltage.

∙ 12y agoIn this context, the abbreviation 'd.c.' (direct current) is used as an adjective to describe a voltage. We can use 'a.c.' (alternating current) in much the same way, e.g. 'a.c. voltage'.
So, a 'd.c. voltage' is one whose magnitude and direction are constant.

How much resistance required to convert 12V DC to 10.5V DC?
How much current? Volts/Amps = Ohms. In your case Volts = 1.5
Rms value defination?
Because alternating current (AC) voltage varies over time, to the positive and negative, an actual AC voltage measurement will not be the same as a DC voltage measurement. For example: 5 volts DC is 5 volts constantly, viewed over time. The average voltage is 5 volts. 5 volts AC (from zero to peak) is not actually 5 volts constantly, but varies between 5 volts and 0 volts over time. The average voltage will not be 5 volts. Using RMS AC values is designed to make AC and DC measurements equivalent, for example 5 volts DC and 5 volts RMS AC are almost identical.
Can a Hp scanner with a non functioning power adapter with an output of 12 volts dc 1.25a be replaced with an adapter with output 16v dc 1.3a?
You give it more volts and it will burn out something!!
Can an 8 volt DC security camera operate on 12 volts DC in a car without burning up?
No
500 volts rms is equivalent to what dc voltage level?
it will be no DC not unless diodes and capacitors are applied. rephrase the question
How do you calculate the ac amps when you have the DC volts DC amps and the ac volts?
the answer is dc volts are rectified from ac volts and the amperage will be the same unless you account for the slight drop from the rectifier. dc volts from a battery have no relationship to ac volts. you can derive ac volts from a dc source using an inverter.
Is 100 amps 48 volts DC the same 12 volts DC?
No.
How many volts are in a auto battery?

13.5-16 volts DC
Is a car cigarette lighter socket ac or dc?
12 volts DC
The working voltage of a capacaitor is rated in ac or dc volts?
DC
How can you change a dc voltage variation from 170 volts to 340 volts in to a constant 220 v dc or 415 Volts 50 Hz 3 pH ac?
I Can Not answer. It is my question.
How many volts should your fuel pump be getting?
12 volts DC.
How many volts does a car cigarette lighter put out?
12 volts DC.
How you can get twelve volts direct current from forty volts direct current?
one way is a voltage regulator, another is a DC to DC converter
