Paper Details

However, a transformer can be used to "transform" resistances, making them behave electrically as if they were larger or smaller than they actually are.
(a) Sketch the primary and secondary coils of a transformer that can be introduced between the amplifier and the speaker in Figure to match the impedances.
(b) What must be the turn?sratio?
