3. The flow of electrons that creates an electric current.
1) Electricity
The flow of electrons that creates an electric current.

4. A subatomic particle with a negative charge.
2) Electron
A subatomic particle with a negative charge.

5. An electric charge built up on persons or objects through friction.
3) Static Electricity
An electric charge built up on persons or objects through friction.
Static = Stationary
Not moving!

6. The flow of electricity through a cable, wire, or other conductor.
4) Current Electricity
The flow of electricity through a cable, wire, or other conductor. DC
Direct
Current AC
Alternating
Current

7. 5) Alternating Current (AC)
An electric current that regularly reverses direction. Ex) Outlet

8. An electrical current that flows in only one direction.
6) Direct Current (DC)
An electrical current that flows in only one direction.
Ex) Battery

9. 7)Circuit
The route in which an electrical current can flow, beginning and ending at the same point.

10. 3 Parts of a Circuit Energy Source Ex) Battery, Outlet, etc.
Energy Collector/Load
Ex) Light bulb
Energy Pathway
Ex) Wire

11. Circuit Symbols

12. Circuit Diagram

13. 8) Series Circuit
A circuit having one path for the electricity to flow.
If one bulb goes out, the circuit is open and they all go out!

14. If one bulb goes out, the rest can stay on w/ their own path!
9)Parallel Circuit
A circuit having MORE than one path for the electricity to flow – “branches”.
If one bulb goes out, the rest can stay on w/ their own path!

15. Series & Parallel Circuits

16. 10) Resistance
Measures how difficult it is for electricity to pass through an object.
SI unit = Ohm Ω Ω

17. Electrical Resistance
Low Resistance
Easy to get through
Good Conductors (copper, gold, etc)
Large/Thick Wires
High Resistance
Tough to get through
Good Insulators (glass, rubber, etc)
Small/Thin Wires

18. A material that allows electricity to flow through it easily.
11) Conductor
A material that allows electricity to flow through it easily.
{Poor Insulator}

19. A material that DOES NOT allow the transfer of electricity easily.
12) Insulator
A material that DOES NOT allow the transfer of electricity easily.
[Poor Conductor]

20. {The Force or Push of Electricity}
13) Volt (V)
Measures
Electrical Pressure
{The Force or Push of Electricity}
SI Unit = Volts

21. [The Volume of the Current]
14) Amp
Measures
Electrical Current
[The Volume of the Current]
SI Unit = Ampere.

22. Ω 15) Ohm SI Unit = Ohm Measures Electrical Resistance
{How difficult it is for the current to pass through}
SI Unit = Ohm

23. Plumbing Pipe Analogy Voltage/Volts (V) = Water Pressure
It determines how fast the electrons will travel through the circuit.
Current/Amps = Flow Rate
A measure of the volume of electricity that flows past a given.
Resistance/Ohms = Pipe Size
Measures the difficulty of electric flow

24. Current is equal to the voltage divided by the resistance.
Current Formula
Current is equal to the voltage divided by the resistance.
I = V/r
I = Current
V = Voltage
r = resistance

25. An electric spark discharged in the atmosphere.
16) Lightning
An electric spark discharged in the atmosphere.

26. In electrons, the absence of flow through with electric current.
17) Open Circuit
In electrons, the absence of flow through with electric current.

27. 18) Closed Circuit
An electric current providing an uninterrupted, endless path for the flow of the current.

29. Attraction for iron associated with electric currents
19) Magnetism
Attraction for iron associated with electric currents

30. 20) 3 Things Needed to Create Electricity
