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.....$V$

In a transformer,$220 \ V$ $AC$ voltage is increased to $2200 \ V$. If the number of turns in the secondary coil is $2000$,then the number of turns in the primary coil will be:

How does a transformer affect the voltage and current?

The coils of a step-down transformer have $500$ and $5000$ turns. In the primary coil, an $AC$ current of $4 \,A$ at $2200 \,V$ is sent. The value of the current and potential difference in the secondary coil is:

The output voltage of an ideal transformer,connected to a $240 \, V$ $a.c.$ mains,is $24 \, V$. When this transformer is used to light a bulb with rating $(24 \, V, 24 \, W)$,calculate the current in the primary coil of the circuit.

In a step-up transformer,if the ratio of turns of primary to secondary is $1:10$ and the primary voltage is $230 \, V$. If the load current is $2 \, A$,then the current in the primary is.......$A$.
