A step$-$up transformer is designed to have an output voltage of $2200$ V $($AC$)$ when the primary is connected across a $110$ V $($AC$)$ source.$($ rms is root mean square$)$

$$

If the primary winding has $86$ turns, how many turns are required on the secondary$?$

If a load resistor R across the secondary draws a current of $1\mathrm{.}40$ A$,$ what is the current in the primary, assuming ideal conditions? $($ Ans to a and b have one common choice $)$

$($a$)($b$)$

A$.172028$ A$$

B$.281420$ A$$

C$.430\mathrm{.}07$ A$$

D$.86014$ A$$

E$.140710$ A
