The primary winding of an electric train transformer has 200 turns,and the secondary has 50.If the input voltage is 120 V(rms),what is the output voltage?
A) 30 V
B) 15 V
C) 10 V
D) 480 V

Question

Quizplus · Accepted Answer

The output voltage can be calculated using the transformer turns ratio formula: V_secondary = (N_secondary / N_primary) * V_primary. Here, V_secondary = (50/200) * 120 V = 30 V.
