You want the output current from the secondary coil of a transformer to be 10 times the input current to the primary coil.The ratio of the number of turns N₂/N₁ must be A)100 B)10 C)1 D)0.1 E)0.01

Question

Quizplus · Accepted Answer

The current ratio in a transformer is inversely proportional to the turns ratio. To increase the current by a factor of 10, the turns ratio N2/N1 must be 1/10, or 0.1.
