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 vs. 10), the current in the secondary will be half of that in the primary (5.0 A / 2 = 2.5 A).
