A transformer may be used to provide maximum power transfer between two AC circuits that have different impedances Z1 and Z2. This process is called impedance matching. (a) Show that the ratio of turns N1/N2 for thistransformer is N1/N2 =√Z1/Z2(b) Suppose you want to use a transformer as an impedance- matching device between an audio amplifier that has an output impedance of 8.00 kΩ and a speaker that has an input impedance of 8.00 Ω. What should your N1/N2 ratio be?
