1. Electric Circuits

2. Electric Circuits a continuous path in which electrons can flow.
*continuous indicates that if it is not complete and continuous, electrons will not flow.

3. Requirements? What are the components of a Circuit?
Electrical Energy ie. battery
Conducting Wires ie. copper wire
Control Device ie. switch
Load ie. light bulb
*Remember good conductors are metals ie. Copper wire, vs. insulators like plastic/rubber which surround the copper wire to prevent against discharge to the person holding the cables.

4. What do these parts do?
Load: converts electrical energy into other forms of energy ie. light bulb, motor, heaters, fans
Switch: a device in an electric circuit that controls the flow of electrons by opening (or closing) the circuit
On- circuit is closed, electrons can flow
Off- circuit is open, electrons stop flowing

5. Conducting Wire: provides a pathway for electrons to flow from one part of a circuit to another Energy Source: provides the electrons for the circuit

6. Section 12.2
A) read pages
B) answer questions 3-6 (10 min)

7. Electric Circuit Symbols (page 551) Copy out table 1- +
Source of Electrical Energy =Electric Cell
Electrical Conductor = Connecting Wire
Control Device = Switch
Load = Lamp
