SUMMARY
The internal resistance of a source can be accurately determined using the formula: open-circuit voltage divided by short-circuit current. This method is a fundamental principle in electrical engineering, ensuring precise calculations of a source's efficiency. The discussion confirms that this rule of thumb is valid and provides a straightforward approach to understanding internal resistance in practical applications.
