Transcript AC Source Tx and Thevenin
Lesson 23 AC Source Tx AC Thèvenin Learning Objectives Construct equivalent circuits by converting an AC voltage source and a resistor to an AC current source and a resistor. Apply Nodal Analysis to an AC Circuit. Review DC Source transformation Source transformation is the process of replacing a voltage source vs in series with a resistor R by a current source is in parallel with a resistor R, or vice versa. vs vs is R or is R AC Source transformation A voltage source with impedance Z in series is the same as a current source with an impedance Z in parallel. Example Problem 1 Convert the voltage source to a current source: Example Problem 2 Using source transformations, determine the voltage drop VR across the 3 ohm resistor and the current IR through it. Example Problem 3 Using source transformations, determine the voltage drop Vab across the 10 ohm resistor. Nodal Analysis Example 17.12 in Text.
