Circuit Bench
Two paths. Three meters. One suspiciously quiet branch.
Make a prediction. Try it. Compare.
Start with a switch, then explore series and parallel paths. Record readings and use them to explain each discovery. Hints and retries are free.
This is an ideal resistor model, not a real wiring guide. It ignores heating, changing currents and source limits. No batteries, tools, mains electricity or physical build are needed. Practice does not award grades or coins.

Source: 6 V (fixed).
Current: I = V / R.
1 A = 1,000 mA.
- Total current
- Through A
- Through B

Fun fact: In a series path, the same steady current passes through every resistor. It is not used up along the way.
