What is the single variable?
single variable is a that variable which works witout the interaction of other.it does not concern with any other variable
What is the amperage of a 20 HP 240v single phase motor?
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
What are the Application of single phase induction motor?
Split-phase motors are used in many applications that require a medium amount of performance from a single phase source. Many of the motors used in homes that are supplied by single phase power are split-phase motors. Some applications include running fans, blowers, water pumps, air compressors, conveyor belts, and more. The only limits on the applications that can use split-phase motors are the availability of single phase power and the charectoristics of the motor itself.
Do all single phase motors have a start and run winding?
No, commutator motors as used in vaccum cleaners for example do not use a starting winding. Single-phase induction motors need a starting winding without which they will start in either direction if given an initial twist.
What starting device is used on single phase fractional horsepower compressor motors?
A centrifugal switch is used on the starting winding of fractional HP motors. It is used to start the motor one the start winding and at a predesignated rotational speed the switch opens to de-energize the start winding and the motor carries on running on the run winding. Another device that should be on compressor motors is an unloader valve. Sometimes it is electrical driven and other times it is mechanical. It is used to used to unload the pressure from the compression cylinders. Without this pressure being unloaded the motor has to start against the pressure in the cylinder head and the added current draw on the motor is sometimes enough to trip the overload protection of the motor.

What is the advantages and disadvantages of single phase and three phase?
Single phase inherently requires less equipment (it's cheaper). Three phase motors are more efficient than single phase.
What is the single variable?
single variable is a that variable which works witout the interaction of other.it does not concern with any other variable
Would a row of washers with inverter drives connected to single phase panel board cost the same to run as it would set up on three phase panel board?
three phase would be cheaper for running motors are more efficient single phase is only used for small motors and loads where operating economy is not a concern
The clearance ratio for a single stage compressor?
The ratio of clearance volume and the volume of the compressor
How do you write 4sin6xcos6x as a function of a single variable?
4 sin(6x) cos(6x) is already a function of a single variable. The variable is ' x '.

When a variable is by it self do you put a one next to it?
no. It is generally known that a single variable represents 1 of that variable.
What is the degree of a polynomial having one term and single variable?
It depends on the power to which the single variable is raised in that one term.
The single variable that is deliberately changed in the experiment is the?
Independent variable. The dependent variable is the one that is affected by the independent variable, for example-y=2x+2This is the equation of a line. X is deliberately changed to find y hence - y is the dependent variable and x is the independent variable.
Why would three phase be used instead of single phase?
Three phase electricity is used instead of single phase for industrial situations. Industries use three phase electricity instead of single phase to operate electric motors driving heavy machinery. Three phase electrical motors produce more power from the same amount of electricity and maintain steadier speed. Small portable motors such as drills and mixers use single phase. Motors used around the house are single phase. Motors used to run large industrial machines use three phase.
