In a power supply the ac mains voltage with an rms value of 220 V is
applied to the primary winding of a step-down transformer. The number
of turns in the primary and secondary windings are 800 and 30
respectively.
(i) what is the peak value of the voltage induced in the secondary
winding.
(ii) If the secondary winding is connected to a resistive load of 1 kOhms,
what are the rms values of the currents that flow in the primary and
secondary windings? (Assume an ideal transformer operation.)
I think I have part (i) calculated, but not sure how to approach part (ii).
