Hi guys,
The problem isn't with the question itself its more to do with the fact about how they got Z and R. Just need some clarification.
In every other AC power question. I have always worked out impedance with whatever parameters I had be it P/I^2 or V/I. I'm confused as to what the difference here is? Now I'm being thrown off and don't know what I'm calculating in other questions :S
Both of those formulas work out 'R' as can be seen here..so why are they getting two different numbers?
Thank you in advance guys
