425. 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
A transformer requires a changing current to induce voltage; with stabilized DC, the secondary voltage drops to zero.
