Question

the primary coil of a transformer has 480 turns, and the secondary has 112 turns. when an ac voltage of 28.0 v is applied to the primary, what is the output voltage in the secondary?

Answer 1

The voltage of the secondary will be 36 V.From the given conditions primary transformer has 3 times as many turns in the secondary coil.

What is induced voltage?

Electromagnetic induction is what causes the induced voltage. Electromagnetic induction is the process of generating emf (induced voltage) by subjecting a conductor to a magnetic field.

Given data;

No turns in the primary coil,$\rm N_p = 480 turns$

No turns in the secondary coil,$\rm N_s = 112 turns$

The voltage of the primary coil,$\rm V_p = 28 v$

The voltage of the secondary coil,$\rm V_s = ?$

For a transformer,

$\rm \frac{V_p}{V_s}= \frac{N_p}{N_s} \\\\ \rm \frac{28}{V_s}= \frac{480}{112} \\\\ V_s = 6.53 \ v$

Hence the voltage of the secondary will be 36 V.
