What will happen if we short the secondary side of a transformer …
The short circuit in the secondary coil keeps the magnetization of the transformer core close to zero, making the primary coil behave mostly as a short circuit (or rather low resistance) as well. If you open the secondary coil, what behaved as a short circuit in the original circuit suddenly becomes an inductivity that will strongly resist any …
