◆ CircuitForge Learn 🎓 Teach 🗺️ Adventure 🤝 Together 🔁 Review ⋯ More 🧭 My Journey Teach the Cast Some of CircuitForge’s cast are still learning. When you teach them, YOU learn it best — catch what they get wrong, then quiz them.
✕ Teach Flow You be the teacher — Flow is still learning. Helping Flow figure it out is the practice. (Flow's progress stays on this device; nothing is sent anywhere.)
🎓 In a minute you'll be the teacher. Get ready to teach Flow: electric current is conserved around a single loop.
In a single series loop, the same current flows through every part. Bulbs use energy, not current.
Teach the connections
Show how the circuit ideas connect You've helped them one at a time. The real understanding is how the ideas CONNECT — teach that next.
Flow (current (electrons moving)) × Damp (resistance (the slowdown))
Flow is the current; Damp is the resistance. For a fixed battery, how does one affect the other?
More resistance → less current (I = V ÷ R) — Damp throttles Flow They're independent — resistance doesn't change the current More resistance → more current (they rise together)
Flow then says: “I doubled the resistance, so the current should double too.” — is that right?
No — doubling resistance HALVES the current (I = V ÷ R); they move opposite ways Right, more resistance means more current
The link: Ohm's law ties them — current is voltage divided by resistance, so Damp and Flow move in opposite directions.
Turn resistance up, watch current go down — same law, two characters.
Branch (series vs parallel topology) × Flow (current)
Branch sets series-or-parallel; Flow is the current. How does the topology change the current?
Series = one path, same current throughout; parallel = the current splits between branches Topology doesn't matter — current is the same in series and parallel In series the current splits; in parallel it stays together
Branch then says: “In a parallel circuit the same current goes through every branch, just like series.” — is that right?
No — in parallel the current DIVIDES among the branches; only series has one shared current Right, parallel branches all carry the full current
The link: the wiring layout is what routes the current — Branch decides, Flow follows.
One path or many — the topology writes the current's route.
Capstone — design a safe little flashlight circuit Build a flashlight: a bulb that lights when a switch is pressed, without burning out. Each part needs ONE cast member's idea.
What PROVIDES the pressure to drive the current?
Who do you bring in?
Push — a battery: the voltage source Damp — a resistor Branch — the wiring layout
What LIMITS the current so the bulb doesn't burn out?
Who do you bring in?
Damp — a resistor to throttle the current Push — more battery voltage Store — a capacitor to hold charge
How do you wire the switch so it controls the WHOLE circuit?
Who do you bring in?
Branch — put the switch in SERIES, so one press breaks the single path Branch — wire the switch in parallel so the bulb stays on Coil — add an inductor
The synthesis: voltage drives it, resistance protects it, and a series switch controls it — three ideas, one working flashlight.
Push, Damp, and Branch together — that's a circuit, not three separate facts.
