so I'm going thru "Introduction to Electronics: DC/AC circuits" by Stephen Harsany, and it's great, but the typos are killing me! So I need help determining if the text leaves out a crucial piece of info.
Given a primary circuit with an AC voltage of 10v, a resistance of 200 Ohm, and a secondary circuit with simply "R load" attached, find the turns necessary in the transformer for maximum power transfer. The problem as I see it, is we don't know what the load is. I mean heck, we have a primary with an impedance of 200 Ohm, why not just have a 1:1 transformer and a load of 200 Ohms as well, there you go, maximum power transfer.
The answer in the back of the book btw is 3.16:1. Which to mean seems to indicate that they left off the fact that R load was supposed to be 20 Ohm. The 10 VAC doesn't factor as far as max power transfer, right? It's extra info we don't need.
Please correct me if I am wrong. Thanks in advance. Mark
