Component resistor resistor capacitor capacitor Actual value 10 Ω 820 Ω 1 mH 100 mH Measured value 14.8 Ω 820.6 Ω 1.01 mH 108.8 mH 1. Then it is required to calculate the value of V L and the complex powers using the real value of the elements. So the circuit would look like: V L = 07 . 0 5 . 3 = 10 × 319 . 2 + 5 . 3 = ) π 62 . 219 + 4 . 835 ( ) 6 . 820 +

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
