What is the full lode current of a 25kw 400v3phase induction motor having 50.8 power factor?
Power factor is the cosine of the phase angle between voltage and current. As such, it will have a value between +1 and -1. 50.8 is not a valid value. Please restate the question.
Another Answer
Power factor is sometimes expressed as a percentage, rather than per unit, so presumably you are referring to a power factor of 50.8% or 0.508. Presumably, too, by 'full-load current', you are referring to the machine's line currents.
So, you can use the following equation to determine the line currents:
Since P = 1.732 E (line) I (line) x (power factor)
So, I (line) = P / [1.723 E (line) x (power factor)]

What is current controlled current sources?
A unidirectional current controller device is a type of electrical on/off switch. In order for an item to work that is plugged into a particular outlet, the switch must be in the on position. It is like having lamps plugged into outlets that are controlled by only one switch.

Does a increase in current limit result in increase in electrical consumption?
Not necessarily. If a load has a low power factor, it will be drawing more current than necessary, but its energy consumption will be no different from it having a high power factor.

What is the current in 1KVA Transformer?
Tis question is incompleet.1000 va =1 kva.This is the power capacity of transformer. A transformer having 2 currents Primary current and secondary current . for that we required both voltage. Simply we can calculate by a formula Voltage x Current x 0.8(power factor)=1000.
