SUMMARY

The discussion centers on the method for finding Thevenin equivalents in electrical circuits, specifically focusing on Thevenin resistance (R_Th). It confirms that an arbitrary test voltage source, such as 5 V, can be applied at the terminals to determine R_Th using the formula R_Th = V_test/I_t, where I_t is the current through the test source. This approach is valid and allows for flexibility in choosing test source values.

Homework Statement


When finding the Thevenin resistance for a circuit, there is a method involving applying either a test voltage source or a test current source at the terminals a and b. My teacher didn't really go into this in very much detail so I was wondering if you can specify any value for the test sources? i.e. I can place an arbitrary voltage source (say 5 V) at the terminals, find the current I_t through the source and have R_Th = 5/I_t?

Thanks
