Variable DC power supply is:
Variable - you can adjust it
DC - direct current, electrons (electricity) flows in only one direction
power supply - power supply
Together, it's an adjustable one-way power supply

∙ 13y agoDC stands for Direct Current. It's a current that only flows in ONE direction. You get this kind of power from batteries and such. (As oppose to AC, which is Alternating Current. That's current that flows in two directions, continually reversing. You get AC supplied from the mains.)

Applications of variable DC power supply?
Variable dc supply is applicable in loads that are variable.
Why DC supply is used in control circuit?
dc supply is used for control circuit because dc current is an independent source .
What is the value of ripple in the ideal dc power supply?
In an ideal DC power supply, there is no ripple.
What the conclusion that can take in multiple dc power supply?
conclusion of dc power supply 9V
How you convert a power supply into 12v DC?
DC 12V power supply can convert 110/220V AC power source to 12V DC.
What are the applications of variable DC power supply?
variable dc supply are used to get desired amount of dc supply
Applications of variable DC power supply?
Variable dc supply is applicable in loads that are variable.
Where can one purchase a variable DC power supply?
You can purchase a variable DC power supply online from retailers such as Amazon. Once on the website, type "Variable D/C Power Supply" into the search field at the top of the page and press enter to bring up the items.
What are 2 mathod of speed regulation in DC motor?
The speed of a dc motor can be regulated by the following means:By varying the supply voltage and byUsing a variable rheostat.
Can TV be run by DC supply?
no... run tv with dc supply
I want to make power supply from 220 V AC to 300 V DC variable adjustable someone please help me or give me a link of workable circuit?
You could try using a simple variac to make the power supply from 220 V AC to 300 V DC variable adjustable. This will work just fine if you don't have a workable circuit.
What is a Variable 0 - 12V dc power supply?
A variable power supply has a control to adjust the DC output voltage from 0 to 12 volts. It is used for testing electric project's such as amplifiers and other electric devices. It can be used to replace other fixed voltages power supplies such as the srandard 3 volt, 5 volt, 9 volt and 12 volt units.
How can an ac generator be converted to DC generator?
It may not be possible to physically convert AC generator to DC generator. What can be done is that 'Rectifier' of suitable capacity can be connected to the out put of AC generator to get DC supply.
What are DC Choppers?
Dc chopper is a static device which converts constant dc source to variable dc.
How to calculate the resistance to step down DC voltage?
Connect a variable resistance across DC source (fixed ends of variable resistor or Rheostat) and take decreased DC output across its one fixed terminal and other variable terminal of variable resistor. Other method is connect variable resistor in series with DC output and load, vary the resistance and take decreased DC voltage as required.
Why transformer can not be used in dc supply?
The transformer cannot be used in the DC supply because it keeps on alternating its current, whereas the DC supply current should be constant.
What are choppers?
Dc chopper is a static device which converts constant dc source to variable dc.
