When finding the Thevenin impedance of an ac circuit, the independent voltage sources are replaced by
- short circuits
- open circuits
- resistors equal to the source impedance
- capacitors
Answer
A. short circuits
Solution
To find ZTh every independent voltage source is set to zero volts (a short circuit) and every independent current source to zero amperes (an open circuit).
