The three factors required to determine power requirements for a task are?
The answer is Force, Distance, and Time.
What are the factors that are used to determine power?
Watts = Volts x Amps x Power Factor Power Factor is one for a resistive load and decreases toward zero as the voltage and current waveforms get out of phase with various inductive loads.
How kvar is calculated?
There are various ways in which you can determine the reactive power (in reactive volt amperes) of a load. From the practical point of view, you can use a voltmeter and an ammeter and use the product of their readings to determine the apparent power (in volt amperes) of the load, and a wattmeter to determine the true power (in watts) of the load, then find the vectorial difference: (reactive power)2=(apparent power)2-(true power)2
