If the illustrated device in figure "B" has a step-up ratio of 10 to 1 what voltage would be measured at the secondary shortly after the primary of the device is connected to 110 volts DC and the primary current stabilized with a current of 12 amps? EL-0055
A) 1000 volts

I think this is referencing Inductive Resistance in Transient Conditions. Immediately after receiving current, the inductor will attempt to resist the change and then get with the program at its own pace.

trick question, Figure B is showing an AC source while the question is saying that a DC voltage is applied.
