1. Referring to the given circuit, what is VTH if VS = 12 ∠0° V?

2. Referring to the given circuit, find ZTH if VS is 180° V.

3. Determine VTH when R1 is 180 Ω and XL is 90 Ω.

4. The two basic components of a Thevenin equivalent ac circuit are
5. One circuit is equivalent to another, in the context of Thevenin's theorem, when the circuits produce the same voltage.
6. For the given circuit, find VTH for the circuit external to RL.

7. Like Thevenin's theorem, Norton's theorem provides a method of reducing a more complex circuit to a simpler, more manageable form for analysis.
8. The superposition theorem is useful for the analysis of single-source circuits.
9. Referring to the given circuit, L
