  2. AC Circuits All the equipment in this operating room use alternating current circuits.

  3. Resistance

  4. Capacitance

  5. Capacitive Reactance, XC

  6. Example 1A Capacitor in an AC Circuit For the circuit above, the capacitance of the capacitor is 1.50 mF, and the rms voltage of the generator is 25.0 V. What is the rms current in the circuit when the frequency of the generator is 5.00 × 103 Hz?

  7. Resistive Circuit

  8. Current and Voltage in a Capacitive Circuit In a circuit containing only a capacitor, the instantaneous voltage and current are not in phase. Instead, the current leads the voltage by one-quarter of a cycle or by a phase angle of 90°.

  9. Inductance

  10. Inductive Reactance, XL

  11. Example 2An Inductor in an AC Circuit The circuit in Figure 23.6 contains a 3.60-mH inductor. The rms voltage of the generator is 25.0 V. Find the rms current in the circuit when the generator frequency is 5.00 × 103 Hz.

  12. Current and Voltage in an Inductive Circuit The instantaneous voltage and current in a circuit containing only an inductor are not in phase. The current lags behind the voltage by one-quarter of a cycle or by a phase angle of 90°.

  13. A Comparison:Capacitive versus Inductive The current leads the voltage by one-quarter of a cycle or by a phase angle of 90°. The current lags behind the voltage by one-quarter of a cycle or by a phase angle of 90°.
