Electric curcuits, electromagnetic forces and induction
Across
- 1. Electrical device that transfers electrical energy between two or more circuits through electromagnetic induction
- 3. Input ....... is a device whose properties change when its environment changes(f.g. LDR, thermistor, etc.).
- 5. An electronic component that allows current to flow in one direction only.
- 6. Electrical ........ is the opposition to the flow of electric current in a material.
- 8. A switch controlled by electricity, used to turn circuits on or off remotely and possibly link two circuits together
- 9. If input A is one and input B is also zero in an OR gate, then the output will be .....
- 11. If input A is one and input B is also one in a NAND gate, then the output will be .....
- 12. Electromagnetic ....... is a process of generating electricity from motion.
- 13. ...... = current (A) x p.d.(V)
- 14. A safety device that breaks an electrical circuit when the current is too high.
Down
- 2. ......... current is an electric current that periodically reverses direction.
- 4. A device used to measure the electric current flowing through a circuit.
- 5. A .... effect is when motion between a conductor and a magnetic field creates an electric current.
- 7. A type of magnet in which a magnetic field is generated by electric current flowing through a coil of wire.
- 10. A transformer consists of 3 main parts: a primary coil, a ....., and a secondary coil.
