Consider an electrical transformer has 10 loops on its primary coil and 20 loops on its secondary coil.
-What is the voltage in the secondary coil if the primary coil is supplied with 120 V?
A)120 V
B)60 V
C)240 V
D)480 V

Question

Quizplus · Accepted Answer

The voltage in the secondary coil depends on the turns ratio between the primary and secondary coils. If the turns ratio is 1:2, then the voltage in the secondary coil will be twice that of the primary coil. Therefore, if the primary coil is supplied with 120 V and the turns ratio is 1:2, then the voltage in the secondary coil will be 240 V (option C).
