Thevenin TheoremHardQuestion 31637

Question

Thevenin's theorem replaces a complex linear network (viewed from two terminals) with:
  1. A
    A voltage source only
  2. B
    A current source and resistance in series
  3. C
    A voltage source V_th in series with resistance R_th
    Correct
  4. D
    Two voltage sources in parallel

Correct answer

A voltage source V_th in series with resistance R_th

Explanation

Any linear two-terminal network can be replaced by a single Thevenin voltage V_th (open-circuit voltage) in series with R_th (resistance seen from terminals with sources zeroed).
