What happens if you connect the following in this order: 1) from a battery to the primary in 2) from the primary out to the secondary in 3) from the secondary out to a motor 4) from the motor to the battery I know that transformers usually step up or step down the voltage, but it shouldn't be possible to feed a stepped up voltage and add it to the total voltage right? So what would REALLY happen? Say if it was a step up transformer, the voltage would go up and the current would go down. But in my example, the current that goes through the primary windings would also go through the secondary windings. This complicates things I know, but does anyone have a good answer as to what would happen? Thanks.
