22.17. Set Up: Solve: 22.18. Set Up: From Problem 22.14, For a resistor, For the source, and Solve: (a) (b) (c) Energy is stored and released in the capacitor and inductor but not dissipated. The average rate of dissipation of energy for each is zero. 22.19. Set Up: The angular frequency and the capacitance can be used to calculate the reactance of the capacitor. The angular frequency and the inductance can be used to calculate the reactance of the inductor. Calculate the phase angle and then the power factor is Calculate the impedance of the circuit and then the rms current in the circuit. The source has rms voltage The average power is On the average no power is consumed in the capacitor or the inductor, it is all consumed in the resistor. Solve: and The power factor is (b) (c) The average power delivered to the resistor is The average power delivered to the capacitor and to the inductor is zero. Reflect: On average the power delivered to the circuit equals the power consumed in the resistor. The capacitor and
