When using superposition to find the effect of one source, the other independent voltage sources and current sources are replaced by
- short circuits and open circuits respectively
- open circuits and short circuits respectively
- short circuits for both
- open circuits for both
Answer
A. short circuits and open circuits respectively
Solution
Each ideal voltage source not being considered is set to zero volts (replaced by a short circuit). Each ideal current source is set to zero amperes (replaced by an open circuit).
