A transformer has 200 turns on its primary and 12 turns on its secondary. If the input voltage is 2000 V, what is the output voltage? A) 3.3 × 10⁴ V B) 240 V C) 170 V D) 120 V E) 100 V

Question

Quizplus · Accepted Answer

The voltage ratio of a transformer is given by the turns ratio. In this case, the turns ratio is 200:12, or simplified, 100:6. Therefore, the output voltage is:
Output Voltage = Input Voltage × (Number of Secondary Turns / Number of Primary Turns)
Output Voltage = 2000 V × (12 / 200)
Output Voltage = 120 V
