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

$A$ step-up transformer connected to a $220 \,V$ $AC$ line is to supply $22 \,kV$ for a neon sign in the secondary circuit. In the primary circuit,a fuse wire is connected which is to blow when the current in the secondary circuit exceeds $10 \,mA$. The turns ratio of the transformer is:

$A$ step-up transformer operates on $220 \,V$ and supplies a current of $2 \,A$. The ratio of primary and secondary windings is $1:20$. The current in the primary is (in $\,A$)

The output voltage of a transformer connected to a $220 \, V$ line is $1100 \, V$ at a $1 \, A$ current. Its efficiency is $100 \%$. The current coming from the line is ........ $A$.

$A$ $220\, V$ input is supplied to a transformer. The output circuit draws a current of $2.0\, A$ at $440\, V$. If the efficiency of the transformer is $80\%$,the current drawn by the primary windings of the transformer is ..... $A$.

$A$ power transformer (step-up) with a $1:8$ turn ratio has $60\, Hz, 120\, V$ across the primary; the load in the secondary is $10^4\ \Omega$. The current in the secondary is:
