In transformer Np= 500, Ns=5000. Input voltage is 20 V and frequency i...
Solution:
Given, Np = 500, Ns = 5000, Vin = 20V, and f = 50 Hz.
Let Vout be the output voltage and f' be the output frequency.
Using the transformer formula, Np/Ns = Vp/Vs, we get
Vout = (Vin*Ns)/Np = (20*5000)/500 = 200V
Hence, option (1) and (3) are the correct answers.
Now, let's calculate the output frequency.
Since the frequency is inversely proportional to the number of turns, we have
f' = (f*Np)/Ns = (50*500)/5000 = 5 Hz
This is not one of the options given, so we need to re-calculate.
We know that the output frequency can be changed by changing the number of turns on the secondary coil.
Let's assume that the actual output frequency is 50 Hz, which is the same as the input frequency.
In that case, we have
Ns/Np = f/f' = 50/50 = 1
Therefore, Ns = Np
But we are given that Ns = 5000 and Np = 500, which means that the output frequency must be less than 50 Hz.
Hence, option (4) is the correct answer.
Final answer: (1) 200V, 40 Hz (2) 100V, 50 Hz (3) 200V, 50 Hz (4) 150V, 40 Hz.
