I've connected various transformers to a circuit (one at a time) in reverse (power supplied to secondary) and I measured the voltages at both windings and found ratios very different from the ones ...
In class, we were given equations for the transformer in terms of number of turns primary/secondary and coupling coefficient K, however effect of distance between coils, presence/absence of core, and ...
Capacitors and inductors are duals of each other. A transformer is made of two inductors, and transfers power through mutual inductance, through the magnetic near-field (right?) Also, you can vary ...
