Misconceptions & Reasoning
📋 What it is
Test "obvious" electricity ideas against evidence — many beliefs about current and batteries are wrong.
🗣️ Coach says
Electricity is full of feels-right-but-wrong ideas: current isn’t "used up" going around a circuit (the same amount returns), a battery doesn’t store electricity ready-made (it stores chemical energy), and electrons actually drift surprisingly slowly. Reason from evidence, not intuition.
🧠 Memory hook
Feels-true ≠ is-true. Current isn’t used up; a battery stores CHEMICAL energy, not electricity.
😂 Giggle
Why did the LED break up with the circuit?
It felt like the relationship had no spark!
😲 Whoa!
Electrons in a wire drift slower than a snail — a few millimetres per minute — yet a light turns on instantly, because the electric "push" travels near light-speed.
✅ Quick check: Is electric current "used up" as it goes around a circuit?
Say your answer out loud first — then reveal.
No — the same amount of current returns to the battery; it’s the ENERGY that gets transferred, not the charge that disappears.
Charge is conserved; energy is what components use.
🧪 Try it! (2 minutes)
Trace a simple loop and note the current is the same on both sides of a bulb — it’s not consumed.
