Circuit Lab

An electricity bench on the screen: batteries, bulbs, switches and resistors. Light a bulb by closing the gap with the right material, control bulbs in parallel, and use Ohm’s law to set a current.

Circuit Lab, a screen from the game

What your child learns

  • Conductors and insulators
  • Parallel circuits and switches
  • Ohm’s law: current = voltage ÷ resistance

How to play

Fill a gap with copper, a clip or a coin (or rubber, wood…), flip switches to light the asked bulbs, then choose the resistor that gives the current the ammeter needs. Four right answers finish a level.

Levels

  1. Level 1Conductor or insulator?
  2. Level 2Two bulbs in parallel with a main switch.
  3. Level 3Pick the resistor for a current.

A tip for parents

Check together which things at home conduct: a key does, a pencil’s wood does not.

Works on phones, tablets and computers, with nothing to install. No ads and no tracking.
