42 - AC CIRCUITS PROBLEM 10 & 11 | Find the Impedance current and the phase angle #knust

In this video, we are going to solve ac circuit problems, finding the impedance, current and phase angle between the current and the source voltage.

Finding the impedance of an rlc circuit.
Z = R + jXL - jXc, where
R is the resistance
XL is the inductive reactance
and
Xc is the capacitive reactance

I am sorry man, it seems like you got the answer wrong, because you used 40 Ohms instead of 400/pi Ohms as stated in the question...I calculated the total impendence is Z=24.951 with the phase angle of -86.42 and finally my current was I=8.0156A with phase 86.4 degrees I used two methods 1) calculating the total effective impedance and then using the source voltage to calculate the total current. 2) Here I used the fact that the total current is equal to the sum of the current in each loop, and they both yielded the same result
