Procedure: 1)Build the circuit below on a breadboard with a 1kHz sine wave of amplitude 5V (V pp =10V). Measuring the actual values for the circuit components using an RLC meter and DMM gives the results below: Using measured values for components: V L =_______________ I L =_______________ S =_______________ 2)AC Power Analysis: a-Vs = ________________ V L =________________ phase angle of V L = _____________ b-V RL =_______________ phase angle of V RL =_____________ I L =________________ phase angle of I L =_______________ 3)Power Factor Correction: a-To correct the load power factor to unity (pf=1), we must put a capacitance C in parallel with the load: Value of C = _____________ Component Nominal Value Actual Measured Value RL 820 Ω R TR 10Ω L 1 1mH L 2 100 mH

### 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.
