- 4. When you have two electric charges that are the same, they will not be attracted to each other, rather, they will be...
- 9. These are the units for measuring voltage.
- 11. This is the relationship that exists between resistance and current. When you increase the resistance, the current will decrease.
- 12. This is the relationship that exists between voltage and current. When you increase the voltage, the current also increases.
- 15. If you have a positive and a negative charge and you hold them close to each other, they will be _____ to each other.
- 16. This device interrupts electrical current and will "break" the circuit so that electrical devices cannot receive electricity.
- 18. This is a form of energy created by positive and negative electrical charges.
- 19. This is the law which describes the relationship between current, voltage, and resistance.
- 20. This component can provide an electrical circuit with voltage. Typically, they have a voltage of 1.5V.
- 22. This is the type of circuit where all resistors share a single pathway to the power supply.
- 23. This material blocks electric charge from moving. Rubber and plastic are examples.
- 24. When an object has the same number of positive charges as negative charges, we say it is...
- 25. This word sounds like "circle" and it describes how we connect electrical components.
Down
- 1. These are the positive form of electrical charge. They reside in the nucleus of an atom and they do not move.
- 2. This can be found to be both positive and negative and it's responsible for the basis of electricity.
- 3. This is the flow of electrons through a conductor.
- 5. These are the negative form of electrical charge. When they begin to flow through conductors, we say that there is "current."
- 6. This is applied to a circuit and it creates electrical current. It pushes the electrons through the conductor.
- 7. These are the units for measuring current.
- 8. This is a material which allows for electric charge to pass through. Oftentimes it exists as a metal.
- 10. This is the type of circuit where resistors (lightbulbs) are connected so that they all have their own pathway to the power supply.
- 13. This impedes, or slows, the flow of electrons through a conductor.
- 14. These are the units for measuring resistance.
- 17. When you walk across carpet with socks on, and get shocked by a door handle, this is the type of electricity produced.
- 21. This component connects other electrical components in an electrical circuit.
