Question

a transformer is used to transform a 230 V mains supply to 12 V for a computer games console. A) the primary coil has 5000 turns. how many turns should there be on the secondary coil​

Answer 1

Answer:

∴The number of turns should be there on the secondary coil is 260.8

Explanation:

A) In the transformer

      $\frac{Vp}{Vs} =\frac{Np}{Ns}$

$\frac{230}{12} =\frac{5000}{Ns}$

$230 Ns =12 X5000$

$Ns=\frac{60000}{230}$

$Ns=260.8$
