QUESTION:
what is the difference between the Kvar and farads, Rating on Power capacitor is for eg: x kvar, and normal capacitor is eg: x farads.

what is the relation between these two?
ANSWER
KVAR : stands for Kilo Volt Ampere Reactance , used to measure maximum reactive power (imaginary) that can the capacitor stands

Farad : unit of measuring the capacitance of the capacitor

No relation between them !

QUESTION :
According to ohms law V=IR that is Voltage and Current are directly proportional to each other but whenever load increases the current increases and the voltage reduces which means inversely proportional how?
ANSWER:
According to ohm's law voltage and current are directly proportional keeping resistance as constant but whenever load increases the current increases and the voltage reduces because Power=V*I so for maintaining constant power when current increases the voltage reduces.so both the conditions are different.
