A pure resistive load is connected to an ideal step-down transformer as shown in figure The primary voltage and the secondary current are 220 V and 4 A respectively. If the load is operated at 50 W, calculate, Ip Vs www www Resistive load Figure Q1 (a) the resistance of the load; (b) the secondary voltage Vs; (c) the primary current Ip; and (d) the turn ratio of primary winding to secondary winding. (e) The material of the core of the transformer is changed from iron to copper. Does the transformer still can operate? Give reasons to support your answer.
