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 → ⭐
