Unit 3 Its Electromagnetic!

1. Circuit : a closed circuit in which the current divides into two or more paths before recombining to complete the circuit
3. Charge : designated positive, negative, or zero, found on the elementary particles that make up all known matter
4. Electricity : A stationary electric charge, typically produced by friction, that causes sparks or crackling or the attraction of dust or hair
6. Cell : An electrochemical cell is a device capable of either deriving electrical energy from chemical reactions
7. : electrical engineering, a conductor is a material which contains movable electric charges
9. Magnet : Any material that exhibits high resistance to electrical current, such as rubber, plastic, or wood
12. : An apparatus for reducing or increasing the voltage of an alternating current
15. : A closed path through which an electric current flows or may flow
17. : An electromotive force or potential difference expressed in volts
18. Field : The space around a magnet in which its magnetic lines of force act

1. Magnet : A magnet that retains its magnetic properties in the absence of an inducing field or current
2. : A flowing movement in a liquid, gas, plasma, or other form of matter, especially one that follows a recognizable course
3. : Electricity involves charged particles at rest or in motion; A form of energy that can be produced by chemical changes
5. : The creation of a voltage difference across a conductive material (such as a coil of wire)
8. Circuit : a complete electrical circuit around which current flows or a signal circulates
10. Generator : any device for converting mechanical energy into electrical energy by electromagnetic induction, esp a large one as in a power station
11. : Change the position, direction, or focus of
13. Circuit : a circuit having its parts connected serially
14. Circuit : An electrical circuit that is not complete
16. : The poles in a magnet can be seen as north and south
