  1. Chapter 16 Inductive AC Circuits

  2. Objectives • After completing this chapter, you will be able to: • Describe the phase relationship between current and voltage in an inductive AC circuit • Determine the inductive reactance in an AC circuit • Explain impedance and its effect on inductive circuits

  3. Objectives (cont’d.) • Describe how an inductor-resistor network can be used for filtering and phase shifting • Explain how low-pass and high-pass inductive circuits operate

  4. Inductors in AC Circuits Figure 16-1. The applied voltage and the induced voltage are 180 degrees out of phase with each other in an inductive circuit.

  5. Inductors in AC Circuits (cont’d.) Figure 16-2. The current lags the applied voltage in an AC inductive circuit.

  6. Inductors in AC Circuits (cont’d.) • Inductive reactance • Opposition to current flow offered by an inductor in an AC circuit • Expressed by the symbol XL • Measured in ohms

  7. Inductors in AC Circuits (cont’d.) • Formula for inductive reactance: where: π = pi or 3.14 f = frequency in hertz L = inductance in henries

  8. Inductors in AC Circuits (cont’d.) • Impedance • Total opposition to current flow by both inductor and resistor • Vector sum of the inductive reactance and the resistance in the circuit

  9. Applications of Inductive Circuits Figure 16-3. RL filters.

  10. Summary • In a pure inductive circuit, the current lags the applied voltage by 90 degrees • Inductive reactance is the opposition to current flow offered by an inductor in an AC circuit • Inductive reactance can be calculated by the formula:

  11. Summary (cont’d.) • Impedance is the vector sum of the inductive reactance and the resistance in the circuit • Series RL circuits are used for low- and high-pass filters
