There's nothing in the U.S. Constitution that bars anyone with dual citizenship from becoming president, but the simple fact that Cruz could claim a Canadian passport or one day vote in a parliamentary election is unlikely to sit well with those who were already doing their best to dub him Canadian Ted..
Definition of transformer: Device that converts an alternating (A/C) current of a certain voltage to an alternating current of different voltage, without change of frequency, by electromagnetic induction. A 'step up' ...
A transformer is an electrical device that is used to change the voltage in alternating current (AC) electrical circuits. The ability of this device to change voltage is a major advantage of AC electricity over direct current (DC).C transformers. You can see that DC voltages could not be changed with the configuration of the transformer. This is because the DC current would not be changing the magnetic field the way AC current does. And this was the reason that AC won over DC when electricity started to be used around the world.
