i was doing some revision,and used an online site for a textbook because we dont get decent ones that tell us what we need to know...

ok i was reading my notes,and i have one method that i understand,but cant tell if its a correct example,and the 2nd one,is an 'answer' to a question i did in an assignment,problem is i completely have no idea what hes doing in it.

thanks alot!

i know its simple,yet my tutor hasnt explained it well in a way i can use.

i have looked at a site but it uses different methods...(listed at bottom)

is this correct ??

Obviously Convert mH or F into Xl/Xc Reactance

eg
5Ω

work out angle if any resistance included =
eg
ta-1= Xl/r
=-53°

Z = 5 Ω
