Thevenin resistance Rth is found
Correct answer: D. between same open terminals as for Etk
- A. by removing voltage sources along with their internal resistances
- B. by short-circuiting the given two terminals
- C. between any two 'open' terminals
- D. between same open terminals as for Etk
Explanation
After deactivating independent sources, the Thevenin resistance is measured between the same two open terminals used to determine the Thevenin voltage. Simply short-circuiting the terminals would remove the port rather than find its resistance.
