How to play
- Move with WASD / Arrows. Interact with a bench using E.
- Use the probe (click nodes in the diagram) to read voltages. Each probe costs 5 s.
- Compute the required value and enter your number (units shown). We simulate to verify — no answers are shown.
- Fix all three benches to unlock the EXIT and escape before time runs out.
Topics: Ohm’s law, diodes, potential divider, internal resistance of a cell.

- Ohm’s law, series/parallel resistance, power.
- Potential divider design \(V_\text{out}=V_s\frac{R_2}{R_1+R_2}\).
- Diode forward drop (idealised fixed \(V_f\)).
- Internal resistance \(E=V+Ir\), terminal p.d., load lines.
