I'm suppose to measure total current, voltage across coil/capacitor/resistor, total active and power factor
How am i connecting my multimeters and wattmeters, can anyone explain with pictures?

Is this a school exercise? The best way for you to learn is to make an attempt, to evaluate the results, and to try to explain why the results may not have been what you expected.
This circuit is simple enough that calculating all those values manually is rather straightforward.
I suggest doing those calculations and comparing the results to waht you get with the meter connections you think will work. If they do not agree, then post again with the calculated results and your circuit showing the meters.

I alredy calculated my values by the way.

I don't think my values are matching though, that i cannot do on a this forum. Clearly there is something wrong with those calculations, i'm getting 16.9 watts for calculated value. That's not the only one, i'm sure there are others.
ZT = 16.26
IT = 1.84
= 72 degrees
S = 55.2 VA
P = 16.9 Watts
IXC = 64 Vars
IXL = 117 Vars
PF = 0.306 lead/lag

Are my multimeters correctly in placed as they should be?
