So I was just reading about transformers from my textbook, and the textbook seems to state that when the resistance on the secondary winding circuit is infinite and no current runs through it thus the power on it P=VI is zero, then, according to the energy conservation law, no current runs through the primary winding as well.
But I can't really grasp the idea. If the resistance on the secondary winding is infinite, shouldn't the transformer just act as a simple inductor for the primary winding? Current still ought to go through it, like in a simple powersource-inductor circuit.
I can totally see that the power on it is zero due to only the reactance of the transformer/inductor, but shouldn't still current pass through it?
Please tell me where I am wrong.
