- ACCORDINGH TO GENERATION PROCESS OF ELECTRICAL ENERGY THE VOLTAGE WHICH PULLS THE ELECTRONS. SO AS THE MORE THE VOLTAGE THE FORCE IS MORE AND LESS THE VOLTAGE FORCE IS LESS. BUT IN CASE OF POWER SYSTEM FOR A CERTAIN LOAD DECREASING IN VOLTAGE GIVES RISE TO INCREASING IN CURRENT. SO WHY THIS HAPPEND BECAUSE ACCORDING TO GENERATION PRINCIPLE THE LOW VOLTAGE WILL ATRACT LESS AMOUNT OF CURRENT THERE BY DECREASING IN CURRENT ALSO.YES FORMULA WISE IT IS RIGHT BUT EVERY FORMULA IS A MIRROR OF NATURAL PROCESS. I WANT TO KNOW HOW PHISICALLY THIS HAPPEN. TELL ME THE WAY HOW I KNOW COMPLETE RELATION OF VOLTAGE AND CURRENT. PLEASE.
This behavior occurs if the system's current is constrained by its power limit. In a power-limited system with a constant load, the current supplied is restricted by the system's maximum power output, not the load's ideal current demand. As long as the power limit governs the system, the power stays constant, and any change in voltage causes the current to adjust to maintain that limit (up to the power constraint, not the ideal current).
However, if the voltage is reduced enough that the required current falls below the system's power limit, the system is no longer constrained by this boundary. At that point, the current will behave as expected: decreasing with voltage for a fixed resistive load.
While drawing current from system the supply voltage could increase or decrease depending on load, the voltage regulation could be positive or negative. With capacitive load the voltage would increase while with inductive and resistive load the voltage would reduced giving positive regulation. Minimum current would be at unity power factor with resistive loading, current would increase with inductive and capacitive loading with same voltage …….
