Consider an electrical transformer has 10 loops on its primary coil and 20 loops on its secondary coil.
-What is the current in the secondary if the current is the primary coil is 5.0 A?
A)2.5 A
B)5.0 A
C)10.0 A
D)20.0 A

Question

Quizplus · Accepted Answer

The transformer's current ratio is inversely proportional to its turns ratio. Since the secondary coil has twice as many loops as the primary (20/10 = 2), the current in the secondary will be half of the primary current (5.0 A / 2 = 2.5 A).
