Applications of variable DC power supply?
Variable dc supply is applicable in loads that are variable.
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...
Can i reduce electric bill by improving power-factor?
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.
How do you reduce the Power dissipation?
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.
What are the applications of variable DC power supply?
variable dc supply are used to get desired amount of dc supply

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 is the price of the cheapest variable power supply?
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
How do you make power supply variable?
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.

How can you reduce rpm of drill?
Most power drills are now VSR. (Variable Speed, Reversible)
What is an external power supply?
A power supply that is designed to be outside the case of the computer. Most laptop computers use an external power supply rather than an internal one to reduce size and weight while the laptop runs on battery power.
What is the difference between a fixed resistor and a variable resistor?
its the colour of the fixed and the variable we define it by its power and name
