The ideal power factor is one (1) or 100% efficiency. Anything less than one means that extra power is required to achieve the actual task at hand. This extra energy, known as Reactive Power, is necessary to provide a magnetizing effect required by motors and other inductive loads to perform their desired functions.

Why Voltage x Current do not equal rated power?
In an AC system power is equal to Voltage x Current x Power factor. Power factor is not constant and depends on the type of the load. Ideal value of the Power factor is 1, where as practically remains less then 1.
What effect do var's have on the power factor of the circuit?
VAr is reactive power, caused by either inductive or capacitive loads. The ideal power factor to have is 1, anything less than that is a loss on the network. The effect of VArs on the circuit though depends. If you have a load that is mainly inductive, then adding more inductive reactance will lower the power factor. However, if you introduce capacitive reactance this will increase the power factor, and the opposite is true if its a mainly capacitive circuit. So VArs will either increase or decrease the power factor depending on the load of the circuit. The ideal situation is to balance inductive reactance with capacitive reactance so they in effect cancel each other out and power factor is 1.
Why inductor have low power factor?
An inductor has a low power factor because it is a reactive device, and the phase angle of the current with respect to voltage is not zero. In fact, power factor is the cosine of that phase angle, which means that a power factor of 1 means no phase angle, which means a resistive load. Anything else represents a reactive load and a power factor less than 1.In an ideal case, with perfect inductors and perfect conductors, the power factor would be zero, i.e. the phase angle would be 90 degrees lagging.
What is the ideal value of ripple factor?
Zero
What is the Ideal value of Stability factor?
1
What is the Fill factor of a cell?
It is ratio of ideal power output upon dummy input. Lesser the fill factor greater will be the efficiency.
Why Voltage x Current do not equal rated power?
In an AC system power is equal to Voltage x Current x Power factor. Power factor is not constant and depends on the type of the load. Ideal value of the Power factor is 1, where as practically remains less then 1.
What happens to the current if the potential difference is stepped-up in an ideal transformer?
In an ideal transformer, if the voltage is stepped up by a factor of x, then the current is stepped down by a factor of x. The end result is that the power, P=VI, is not changed. Again, this is in the ideal case.

What is the difference between unity power factor to 8 power factor?
Power factor does not go above 1. It is the cosine of the phase angle between voltage and current and, as such, can range between +1 and -1, although it should be understood that a negative power factor is mathematically equivalent to a generator - when looking at the load as if it is a motor - or vice versa. Unity power factor is applicable for a resistive load. A typical power factor for a big motor is about 0.92. A theoretical power factor of zero, corresponding to a phase angle of 90 degrees, would mean that the load is purely inductive or capacitive, and that the power supply and conductors are also ideal or theoretical.
