Figure shows an "autotransformer." It consists of a single coil (with an iron core). Three taps Ti are provided. Between taps T1 and T2 there are 200 turns, and between taps T2 and T3 there are 800 turns. Any two taps can be chosen as the primary terminals, and any two taps can be chosen as the secondary terminals. For choices producing a step-up transformer, what are the(a) Smallest,(b) Second smallest, and(c) Largest values of the ratio Vs/V p? For a step-down transformer, what are the(d) Smallest,(e) Second smallest, and(f) Largest values of Vs/Vp?
