Figure 22.28 (c) reads reads reads reads zero because and these voltages are out of phase. reads 21.2 V, the source rms voltage and also the rms voltage across the resistor. 22.29. Set Up: In a parallel L - R - C circuit the impedance is a maximum at the resonance angular frequency of At the resonance angular frequency, Solve: (a) (b) Reflect: is the resonance angular frequency for either a series or a parallel L - R - C circuit. For the series circuit, at resonance the impedance is a minimum and the current is a maximum. For the parallel circuit, the imped- ance is a maximum and the current is a minimum. v 0 5 1 " LC Z 5 R 5 125 V v 0 5 1 " LC

### 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.
