Across
- 5. A student connects a battery, wires, and a bulb so the bulb lights immediately. What type of circuit was built?
- 7. Tiny charged particles move through the wires when a lamp is plugged in and turned on. What is this movement called?
- 8. Two identical circuits use different batteries, causing more charged particles to pass through one wire each second. Which property is greater in that circuit?
- 10. Copper is chosen instead of rubber for household wiring because electric charges move through it easily. What type of material is copper?
- 11. A larger battery causes the charges in a circuit to be pushed with more force. Which electrical property increased?
Down
- 1. A long, thin wire makes it harder for electric charges to move through a circuit. Which property of the wire is responsible?
- 2. A flashlight changes stored chemical energy into another form that powers the bulb. What type of energy flows through the wires?
- 3. A student presses a button that stops the flow of electric charges to a fan. Which device controlled the flow?
- 4. A wire becomes disconnected, and the light bulb immediately goes out. What type of circuit now exists?
- 6. A light bulb lights only after all the wires are connected to form one continuous path. What has been created?
- 9. A remote control stops working until a new source of stored chemical energy is installed. What device needs to be replaced?
