If you take primary or secondary circuit individually, ohm's law holds at all instants....voltage inversely proportional to current is taken considering both the circuits together,ie, its a relation connecting primary and secondary....as per law of conservation of energy,input power and output power must be the same....

What is the difference between PS & metering CT (5p20,0.5 etc.)? Why in PS class CT only Vk is given ? Is PS class CT is more accurate than metering CT?
