Electricity & Circuits
📋 What it is
Electricity is flowing charge; it powers devices only when it can travel a complete circuit loop.
🗣️ Coach says
Electricity is charge on the move. It powers your gadgets by flowing through a complete loop — a CIRCUIT — from a source, through the device, and back. Break the loop (a switch) and the flow stops. Power plants generate this flowing electricity on a giant scale for whole cities.
🧠 Memory hook
Electricity = flowing charge. It only powers a device through a COMPLETE circuit loop.
😂 Giggle
Why did the light bulb fail its exam?
It wasn't very bright!
😲 Whoa!
The electricity in your home’s wires flips direction 50 or 60 times every second (alternating current) — far too fast to notice, but that’s why it’s called "AC".
✅ Quick check: Why must electricity travel a complete loop to power a device?
Say your answer out loud first — then reveal.
Charge needs an unbroken path out and back; a break in the circuit stops the flow entirely.
Current requires a complete circuit.
🧪 Try it! (2 minutes)
Flip a light switch and picture the loop it completes (on) or breaks (off).
