Calculating The Return Ratio
The steps for calculating the return ratio of a source are as follows:
- Set all independent sources to zero.
- Select the dependent source for which the return ratio is sought.
- Place an independent source of the same type (voltage or current) and polarity in parallel with the selected dependent source.
- Move the dependent source to the side of the inserted source and cut the two leads joining the dependent source to the independent source.
- For a voltage source the return ratio is minus the ratio of the voltage across the dependent source divided by the voltage of the independent replacement source.
- For a current source, short-circuit the broken leads of the dependent source. The return ratio is minus the ratio of the resulting short-circuit current to the current of the independent replacement source.

“[The] elderly and timid single gentleman in Paris ... never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.”
