The core of a transformer is made up of:

$A$ transformer has $120$ turns in the primary coil and carries $5 \text{ A}$ current. Input power is $1 \text{ kW}$. To have $560 \text{ V}$ output, the number of turns in the secondary coil will be:

For the given circuit,comment on the type of transformer used:

Write the working procedure of a transformer.

In a step-up transformer, the turn ratio is $1:10$. A resistance of $200 \, \Omega$ connected across the secondary is drawing a current of $0.5 \, A$. What is the primary voltage and current?

$A$ step-up transformer has a transformation ratio of $5:3$. What is the voltage in the secondary coil if the voltage in the primary coil is $60 \, V$ (in $, V$)?
