- 4. The flow of electrical charge (electrons) around a complete circuit per second.
- 5. A measure of the strength of a cell or battery used to send a current around a circuit.
- 8. Units of measurement of voltage, symbol V.
- 10. An electrical region where a charged material or particle experiences a force.
- 11. An electrical property of a material or particle that can be positive or negative.
- 15. The pole of a magnet that points towards the north. (two words)
- 17. The unit of resistance, symbol Ω.
- 18. Two or more electrical cells joined together.
- 19. How difficult it is for current to flow through a component in a circuit.
- 20. Describes an object or particle that has no charge, or in which positive and negative charges cancel out, giving no charge overall.
- 22. Electrical device that uses current flowing through it in one circuit to switch on and off a current in a second circuit.
- 25. A material that conducts charge or energy well, such as a metal or graphite.
- 27. A circuit in which there are two or more paths or branches for the current.
- 28. A circuit in which components are joined in a single loop.
- 29. Imaginary lines that show the direction of the force on magnetic material. (two words)
- 31. A component or machine that spins when a current flows through it.
- 32. A component that controls the current by making or breaking the circuit.
- 33. Be pulled together, for example, opposite poles of a magnet attract and positive and negative charges attract.
- 34. A rod of a magnetic material placed inside a coil to make the magnetic field of an electromagnet stronger.
Down
