Calculate the number of turns in secondary coil from the given figure.
1 Answer
Here ,
primary voltage V1 = 220 V
number of turns of secondary coil n2 = ?
number of turns in primary coil n1 = 500
secondary voltage = 50 V
we know that,
= \(\frac{v_2}{v_1}=\;{\textstyle\frac{n_2}{n_{1\;}}}\)
= \(\frac{50}{220}=\;{\textstyle\frac{n_2}{500\;}}\)
= \(\frac{25000}{220}=\;n_2\)
=113.63
Hence number of turns in secondary coil of the given step down transformer is 113.63 that is 114
