SUMMARY

The discussion centers on the voltage-current equation in a Thevenin circuit, specifically addressing a scenario with a Thevenin resistance of 15 ohms, an open-circuit voltage of 30 V, and a short-circuit current of 2 A. Participants clarify that the voltage-current equation refers to the relationship between output voltage and output current, potentially utilizing Ohm's Law. The task involves deriving an expression that connects these two variables, emphasizing the practical approach of measuring current with an external voltage source.

Homework Statement



I need help with part (b).

Homework Equations




The Attempt at a Solution



The Thevenin resistance is 15 ohms, voltage open circuit 30 V and the short current circuit is 2 A. You can take these for granted, I've confirmed with a friend.

I really don't know what they mean by "voltage-current equation", are they talking about Ohms law?

Write an expression that relates the output voltage to the output current (or current vs voltage).

Consider sticking a voltage source on the output and "measuring" the resulting current.
