Answer Posted / adam
None of these answers seem to understand the apparent paradox. I am happy that transformers obey the law of conservation of energy; if the secondary voltage is double because Ns = 2 x Np then the maximum secondary current must be half of the primary current as VsIs cannot exceed VpIp.
Therefore there are circumstances when the circuit connected to the secondary end of the transformer will violate Ohm's law. This is true even if the a.c. version of ohm's law is used (that is inductance; 2(pi).f.L is included.
Now, why is this?
Can anyone explain?
