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.
Probe $V_o$: still 8 V. Every stage of the chain is the same circuit as far as the 8 k is concerned.
