Question

In a transformer N_p = 500, N_s = 5000. Input voltage is 20V and frequency is 50Hz. What are the output voltage

and frequency-

• A. 200 V, 40 Hz
• B. 100 V, 50 Hz
• C. 200 V, 50 Hz
• D. 150 V, 40 Hz

Answer 1

Answer: (C)

200 V, 50 Hz

Answer 2

Use $\frac{V_{s}}{V_{p}}$ = $\frac{N_{s}}{N_{p}}$ Frequency in transformer remains same.
