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.

The net measured power would appear to be negative, or reversed.
a three phase motor is reversed by switching 2 of the 3 power leads (any two) something is switching the power leads on you
This means that your power is a variable. Just like your regular term can be a variable the power can also be a variable. Ex. 3n 7n 2357n
variable dc supply are used to get desired amount of dc supply
Variable dc supply is applicable in loads that are variable.
The high is power of either variable is the first
No. An expression can have a variable exponent (for instance, 2 to the power x, or x to the power y), but that is no longer a polynomial.
when gate pulse remove when power supply reversed when power supply cut -off
A variable raised to the second power would be refered to as "squared." Some math-based programs like Excel let you enter a power with a carot, ie, "(variable name)^2" if you want to calculate the answer.
degree is the power of variable.. in polynomial it is the highest power of the variable, in differential equations it is the highest derivative, etc..
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.
The base
x is a variable. You need to find the variable to complete the equation. ex. x = 1 x to the power of 5 (1x5x5x5x5x5)
