Q. A transformer is rated 10 kVA, 220:110 V (rms). Consider it an ideal transformer.
(a) Compute the turns ratio and the winding current ratings.
(b) If a 2-load resistance is connected across the 110-V winding, what are the currents in the high-voltage and low-voltage windings when rated voltage is applied to the 220-V primary?
(c) Find the equivalent load resistance referred to the 220-V side.
