Variable dc supply is applicable in loads that are variable.
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.
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...
For a residential consumer, power-factor improvement has absolutely no effect on one's electricity bill. Adding power-factor improvement capacitors at the point of supply will have absolutely no effect upon the operation of the load circuits, but it may act to reduce the supply current. But reducing the supply current will not reduce one's energy consumption.
Answer for mechanical systems:Use oil or grease to reduce friction!Answer for electrical systems:Making the voltage as high as possible is a good way to reduce power loss.ExplanationThe voltage drop along a conductor is proportional to the resistance and to the current carried. (V=IxR) So, for a given quantity of Power (W=VxI), if the voltage is made as high as possible there will be less current flowing and therefore less power loss.

Variable DC power supplies are commonly used in electronics labs, production lines, and testing environments. They are used to power and test electronic devices such as electrical components, circuits, and sensors. Variable DC power supplies are also used in research and development for prototyping and experimenting with different voltage levels.
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.
The cheapest price the writer was able to obtain for a variable power supply was $45.45 for those customers searching in Canada. If one wants to make a home-made variable power supply, it is possible to buy all the needed parts for about $15.00
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.
