Electric Circuits: Follow the Flow

Like Duolingo, but for Electric Circuits: Follow the Flow. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Making the Connection, The Rules of the Road, Tracking and Troubleshooting, and Power and Protection. It starts from scratch.

Key ideas in Electric Circuits: Follow the Flow

  • Electricity must have a return path to the source to flow
  • The source is the origin of the electrical pressure
  • A broken or 'open' loop prevents any work from being done
  • The load is the component that converts electricity into motion, light, or sound
  • The necessity of a complete path for energy transfer
  • Distinguishing between the energy provider and the energy consumer
  • Metals are conductors that allow electricity to move easily
  • Rubber and plastic are insulators that block electricity to keep it on the intended path
  • A switch acts as a bridge that can be lifted or lowered
  • Selecting materials based on their ability to guide or stop flow
  • Electricity cannot jump across air gaps in standard low-voltage circuits
  • Circuit tracing follows a specific direction from start to finish
  • The flow is modeled as moving from the plus (+) to the minus (-)
  • How a switch controls a circuit
  • The standard direction for tracing electrical flow
  • Voltage acts as the 'pressure' in a wire
