If a Transformer have Turn Ratio 5

Answer: A. 500√2 volts

If a transform turn ratio is 5, then the value of voltage is 500√2 volts.

Solution

Transformer turn ratio K=5.

Root mean square value of induced voltage E_1,rms=100 volts,

Root mean square vale of secondary winding =E_2,rms

Transformer voltage (or) turns ratio K=E_1,rms/E_2,rms

So, E_2,rms=k.E_1,rms

E_2,rms=5×100 

E_2,rms=500 volts

Then, peak value of secondary voltage E_2,peak=√2×E_2,rms

E_2,peak=√2×500

E_2,peak=500√2 volts.
