1. The problem statement, all variables and given/known data Sorry for the stupid question, but I want to be sure whether everything is correct. Here is the problem, I think I managed to do all the parts. 2. The attempt at a solution a)ω=2∏f; ω=4000∏ or 12566.37 rads b)Xl = ωL = 4000∏x0.004=50.27Ω c)I1=R x Vac I2=Xl x Vac I3=Xc x Vac d) 3rd Image e) It is stated that I and Vac are in phase. This can be done only if the two reactances(Xl and Xc ) are equal to each other. f) C=1.583 x 10^(-6) g) Here I am not sure that I used the right equation. They ask for the amplitude of the current I. Using the phasor diagram I used I=√((I1)^2+(I3-I2)^2) which gives 0.007, which is I1.
