Obtain a value for the Thvenin equivalent resistance seen looking into the open
Chapter 5, Problem 37(choose chapter or problem)
Obtain a value for the Thévenin equivalent resistance seen looking into the open terminals of the circuit in Fig. 5.78 by (a) finding \(V_{oc}\) and \(I_{sc}\), and then taking their ratio; (b) setting all independent sources to zero and using resistor combination techniques; (c) connecting an unknown current source to the terminals, deactivating (zero out) all other sources, finding an algebraic expression for the voltage that develops across the source, and taking the ratio of the two quantities.
