Hi, I have just been refreshing my theory and was going over a parallel RL circuit, like this one.

The site I was reading had this for the total current

I tried some values as a test but it doesn't give me the correct answer, for total current. eg if I set

V=10V

R=2.5ohm

jXl=5ohm

Then I

I

I

However when I try the formula from the second answer I get 10/(2.5-2j) which following the maths gives me 2.44+1.95j=3.12A

Am I going wrong somewhere or is it the formula?

Thanks

Then I

_{R}=10/2.5 =4AI

_{L}=10/5=2AI

_{T}=√4^{2}+2^{2}=4.47AHowever when I try the formula from the second answer I get 10/(2.5-2j) which following the maths gives me 2.44+1.95j=3.12A
