Circuit Forge
Build a closed loop through battery + resistors that lights the LED — no shorts, no opens.
Goal
Stay inside the target current band given by Ohm's law (V = IR).
Controls
- Drag a wire from one nodeConnect to another node
- Tap a resistorCycle its value (10Ω / 100Ω / 1kΩ)
- Tap the batteryToggle voltage
Scoring
- Current within 5% of target → ⭐⭐⭐
- Within 15% → ⭐⭐
- LED lit at all → ⭐
