AC Circuit Theory Maximum Power Transfer

Fantastic!

Chr!s, thank you. I've been looking at how to get power as watts which will never work without the correct values. Never though of it as a percentage, which by definition is a value.

I've just sent you up to 100 thanks as well. Appreciate your time.

Your welcome. Good luck!

Thanks for the replies! I'm looking to get the maximum power transfer for the load impedance. View attachment 17445 To calculate the power surely requires either current or voltage to which I am only given the 50Hz supply and the calculated impedance. I've attached a drawing (yeah I know!) Chr!s, 'There are two methods, the trial and error to plot from 0 - 3 ohms, or the first derivative method' I've not heard of the trial and error plot, is there any chance (please!) you could elaborate on this. Using either of these applications you can find the maximum power from only Frequency & Impedance? Thanks

did this on microsoft paint from scratch, please excuse as was done at 2:30 Am as I was up :rolleyes2:

will try to do some more bits and pieces for you on here when I can get the time :stuart:

grant,
There's an error in your solution.
The inductor is reactive so you can't just add it to the resistances.

X[SUB]L[/SUB] = j219.9

so Z[SUB]Th[/SUB] = 330.3 + j219.9

and Z=sqrt(R[SUP]2[/SUP] + X[SUP]2[/SUP])

Blame it on it being 2:30am!
Good drawing btw.
