Electricity
Across
- 2. difference the difference in electrical charge between two points in a circuit expressed in volts
- 5. What is the unit for resistance?
- 6. a form of energy caused by the movement of electrons.
- 7. resistor, a battery, and a closed conducting loop What are the requirements for a circuit?
- 8. a device that opens or closes a circuit
- 9. the rate at which charges pass through a given point; how fast charge is moving
- 11. circuit a closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit
- 13. (Amperes) What is the unit for current?
- 14. circuit a complete, unbroken path through which electric charges can flow
- 15. a material that allows heat and electricity to pass through it
Down
- 1. What is the unit for voltage?
- 3. a material that does not allow heat or electrons to move through it easily
- 4. circuit a circuit in which all parts are connected end to end to provide a single path of current
- 5. Law the current in a circuit equals the voltage difference divided by the resistance
- 10. positive end of the battery to the negative end of the battery How does electrical energy flow in a battery?
- 12. a material's opposition to the flow of electric current; when the movement is charge is slowed or more difficult
