hi all.

i am stuck on this question , and i would really appreciate any help you can give.

Q. You are to examine a Sinusodial AC waveform and use single phase AC circuit theory to explain and determine its characteristics.

This may be a very simple qurstion, but i am new to this sort of thing.

thank you

My guess is that the problem is posed to challenge you to demonstrate your understanding of the characteristics of a sinusoidal waveform. Some of the characteristics you need to study are frequency, period, peak-to-peak amplitude, and rms amplitude to name a few.

Try to re-read you textbook or your class notes to determine the theory elements that were taught during that lesson. This could tell us more about the context of the question

i now understand this question, thank you. i just needed to approach it from a different angle.

i do have another question, if anyone can answer it would be a huge help to me.

Q. u sing an oscilloscope you are to measure and determine the performance of a vehicle alternator.

how would i go about setting out this answer, again my mind has gone blank.

any help would be greatly appreciated.
