The Thevenin equivalent

This is the circuit from the lecture, running. Change it and the answer changes with it:

• Click any component value to edit it, or drag components to rearrange.
• The wrench opens a step-by-step analysis — it chooses a reference node and writes the node equations. Leave its Domain on the DC operating point for this deck.
• The crosshairs probe reads a node voltage or a branch current, so you can check any intermediate result rather than only the final answer.

The values are symbols, so there is nothing to simulate yet. Type in the numbers from Worked Example 2 — $V_{Th} = 6$ V, $R_{Th} = 5$ k — hang a 1 k load across $a$–$b$, and probe it: 1 V.
