1 AC Source Exchange Discussion D16.3 Chapter 4 Section 4-11

2 Recall Source Exchange for DC Circuits We can always replace a voltage source in series with a resistor by a current source in parallel with the same resistor and vice-versa.

3 Source Exchange Proof Voltage across and current through any load are the same

4 For AC Source Exchange replace resistors with impedances and use phasor voltages and currents Voltage across and current through any load are the same

5 Problem 4.40 in text: Find I 0 Source Exchange

6 Problem 4.40 in text: Find I 0 Combine current sources

7 Problem 4.40 in text: Find I 0 Use current division Same answer as using mesh analysis
