it is clear that volts equal to the current as per ohms law. is it appliable to the AC power or onl..

Answer / izhar ahmed

Ohm's law is applied for both AC/DC ckts(phyciallly connected) .But for the transformer we cant use it simply it is a magnetic circuit which are magnetically coupled and principles are based on Faraday law of electromagnetic induction(EMI)

Answer / priyadharsini

i think its applicabe for both Ac and DC.

in transformer N1/N2=V1/V2 = I2/I1.
ie when no.of turns in primary increased voltage in primary
increased bcoz its direct propotional. and current is
inversly proportional hence the current will reduced.

i am not sure the above ans.
if correct ans known to anybody inform me too.
