A variable power supply is one whose output voltage (or current) can be adjusted and therefore set to a desired figure. They are used in development and design odf circuits, eliminating the need for possibly many power supplies of different output voltages.
Once a circuit is connected to it, the output would not normally be changed.

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.
Why does an operational amplifier need a power supply?
It doesn't. You can make a differential amplifier with a single power supply.
LVDT's can you have multiple devices on one dc supply?
Yes, you can connect multiple Linear Variable Differential Transformers (LVDTs) to a single DC power supply, provided that the power supply can handle the combined current requirements of all the LVDTs. It's important to ensure that the supply voltage is appropriate for each LVDT and that the total load does not exceed the power supply's rating. Additionally, proper wiring and signal isolation techniques should be used to avoid interference between devices.
Can you use a power supply with more amps and not fry the unit?
you will need to be allot more specific on what you are trying to do here. what is the difference in amps. what is the device Generally speaking it is good practice to only use the power supply that the device is rated for. the biggest issue you will have is this Power = voltage * current (simple version) if the power supply you had was 12v at 1 amps then you ca supply 12Watts of power if the power supply you had was 12v at 10 amps then you can supply 120Watts of power Just because you can supply 10 amps, and all you need is one, means your power supply is bigger than it needs to be. The device will draw what it is intended to draw. Just make sure the voltage matches.
Full form of DC power supply?
DC Power is Direct Current Power Supply.
What are the advantages and disadvantages of variable power supply?
A: A variable power supply has no disadvantage since it can replace a fix power supply. The disadvantage will rest with the additional cost to make one.

What is variable DC supply?
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 Hope you find this useful...
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.

Can you use a potential divider for obtaining variable DC supply from a fixed AC supply?
Power supply providing constant D.C. output voltages from variable A.C. input voltagesThe novel power supply for generating a constant d.c. voltage from a variable a.c. voltage supply line, includes a plurality of switch circuits (10, 12) which monitor voltage levels on respective secondary windings (L,M,H) of a power transformer and as voltage levels change, one of the plurality of switch circuits is selected to charge a capacitor (C1) which provides a range of d.c. voltages which are processed to provide the constant d.c. voltage.
