Answer:
\(N_2=30turns\)
So option (b) will be correct option
Explanation:
We have given that there is a step up transformer in which number of turns in primary coil is 15
That is, \(N_1=15\)
Primary voltage \(V_1=80volt\), and secondary voltage \(V_2=160volt\)
We have to find the number of turns in the secondary \
We know that for the transformer
\(\frac{N_1}{N_2}=\frac{V_1}{V_2}\)
\(\frac{15}{N_2}=\frac{80}{160}\)
\(N_2=30turns\)
So option (b) will be correct option
