22.41. Set Up: Solve: (a) (b) (c) or Reflect: The impedance of the circuit depends only on the absolute value of not on its sign. For the phase angle is positive and for the phase angle is negative. 22.42. Set Up: is the rate at which heat is generated. Solve: 22.43. Set Up: The power factor is unity when and Solve: (a) (b) so Need to add and (c) so Reflect: When the circuit is at resonance (when ), the current is a maximum and the power delivered by the source is a maximum. For any series circuit, the power delivered by the source equals the power consumed in the resistor. 22.44. Set Up: The voltage lags the current when and and Solve: (a) Since add an inductor to make (c) and gives Need to add so 22.45.

### 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.

Kiran Temple University Fox School of Business ‘17, Course Hero Intern

• 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.

Dana University of Pennsylvania ‘17, Course Hero Intern

• 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.
