A transformer has a 1:6 P-S turns ratio and has a primary current of 12 A. What is the secondary current?
A) 2 A
B) 72 A
C) 12 A
D) 6 A

Question

Quizplus · Accepted Answer

The secondary current can be found using the transformer turns ratio formula: $I_s = \frac{N_p}{N_s} \times I_p$, where $I_s$ is the secondary current, $N_p$ and $N_s$ are the primary and secondary turns, and $I_p$ is the primary current. Given a 1:6 turns ratio and a primary current of 12 A, the secondary current is $I_s = \frac{1}{6} \times 12 = 2$ A.
