Lecture 25 figures 1 Fig. 25-1: An RL series network driven by a complex voltage source. Fig. 25-2: A resistor obeys Ohm’s Law. In phasor notation, Ohm’s Law becomes V = R I . Fig. 25-3: An inductor. The I - V relationship for an inductor is V = jωL I . The factor j represents a 90° phase lag of the current relative to that of the voltage. Fig. 25-4: A capacitor. The I - V relationship for an capacitor is V = (1/jωC) I . The factor j represents a 90° phase lead of the current relative to that of the voltage.

Unformatted text preview: Lecture 25 figures 2 Fig. 25-5: We return to the RL series network driven by a complex voltage source to illustrate the Phasor diagram. Fig. 25-6: The Phasor diagram showing the voltages V R , V L and V o for the circuit of Fig. 25-5. Fig. 25-8: The Phasor diagram showing the voltages I R , I C and I o for the circuit of Fig. 25-7. Fig. 25-7: A parallel RC network driven by a complex current source. We will examine the Phasor diagram for these currents....
