A) 200 V, 50 Hz
B) 2 V, 5 Hz
C) 2 V, 50 Hz
D) 200 V, 500 Hz.
Correct Answer: A
Solution :
Given: Number of turns in the primary \[{{N}_{1}}=500\] Number of turns in the secondary \[{{N}_{2}}=5000\] Input voltage \[{{V}_{1}}=20V\] Output voltage \[{{V}_{2}}=?\] We know that \[\left| {{V}_{2}} \right|=\frac{{{N}_{2}}}{{{N}_{1}}}{{V}_{1}}\] \[=\frac{5000}{500}\times 20=200V\] As in a transformer the output frequency of the ac supply remains the same as that of the input supply, the frequency of the output current will be 50 Hz.You need to login to perform this action.
