$A$ current of $4 \text{ A}$ is flowing at $230 \text{ V}$ in the primary coil of a transformer. If the voltage produced in the secondary coil is $2300 \text{ V}$ and $40\%$ of power is lost, then the current in the secondary will be (in $\text{ A}$)

$A$ power transmission line feeds input power at $2300\,V$ to a step-down transformer with its primary windings having $4000$ turns,giving the output power at $230\,V.$ If the current in the primary of the transformer is $5\,A,$ and its efficiency is $90\%,$ the output current would be......$A$

$A$ step-down transformer connected to an $AC$ mains supply of $220 \, V$ is made to operate a $11 \, V, 44 \, W$ lamp. Ignoring power losses in the transformer,what is the current in the primary circuit? (In $A$)

The number of turns in the primary and secondary coils of a transformer are $100$ and $20$ respectively. If an alternating potential of $200 \, V$ is applied to the primary,the induced potential in the secondary will be......$V$.

$A$ power transformer is used to step up an alternating $e.m.f.$ of $220\,V$ to $11\,kV$ to transmit $4.4\,kW$ of power. If the primary coil has $1000$ turns,what is the current rating of the secondary (in $,A$)? Assume $100\%$ efficiency for the transformer.

For an ideal transformer,if $N_S > N_P$,then . . . . . . .
