In a transformer,the primary has $500$ turns and the secondary has $50$ turns. If $100 \ V$ is applied to the primary coil,the voltage developed in the secondary will be.....$V$

How much current is drawn by the primary coil of a transformer,which steps down $220 V$ to $55 V$ to operate a device with an impedance of $275 \Omega$ (in $A$)?

The number of turns in the primary and secondary coils of a transformer are $50$ and $200$ respectively. If the current in the primary coil is $4 \,A$, then the current in the secondary coil is: (in $\,A$)

The ratio of secondary to primary turns in a transformer is $3 : 2$. If the power output is $P$,then the input power,neglecting all losses,must be equal to:

For an ideal transformer with primary voltage $E_{p} = 1000 \, V$ and primary current $I_{p} = 50 \, A$,if the secondary voltage is $220 \, V$ and it supplies power to $80$ houses,what is the equivalent resistance of the secondary circuit (in $\Omega$)?

Write two types of transformer.
