2. What happen ????

3. Matter
Electric charge
Electric current
Electric circuit

4. electric circuit
complete, unbroken path through which electric charges can flow

5. A circuit Is a loop that electric current flow through it.
A circuit cannot have any breaks. It must be a closed circuit.

7. A circuit diagram is a map of a circuit

8. Resistor
Battery
Conductor
Switch

9. Resistor
The volt (V): is a measure of the electrical force provided by an energy source.
Batteries labeled : AA, AAA, C, and D each deliver about 1.5 volts. Ex:The small box-shaped batteries provide up to 9 volts.
Resistor
Battery
Switch

10. amperes, also called amps
Volt
Ohms
amperes, also called amps
a measure of the electrical energy provided by an energy source
measure the amount of resistance to an electrical current
measure how much current moves past a given spot each second in a circuit

11. Resistor

Transform the electric energy into another form .
The ohm (Ω) is the unit of measure for resistance to electrical current.
A typical flashlight bulb has about 20 ohms of resistance.

14. Conductor
nonmetal
Liquids and gases
Metal
Pencil lead
Graphite
Salt water
Pure metal
Mixed metals

18. Insulator help keep the electric charges inside the path way .
What is the role of insulators such as plastic rubber and cloth covering wires and other conductor in a circuit
Insulator help keep the electric charges inside the path way .

19. series circuit

20. Is the circuits that have more than one resistor on a wire.
Electric series
In a series circuit, the current must be able to pass through all the resistors.  

21. Suppose a series circuit has three bulbs . One bulb burns out .
What will happen in the circuit ?

23. series circuit simple to build only 1 path for current to take
advantage
disadvantages
simple to
build
if 1 light goes
out-
all go out
more bulbs
added-
greater resistance

24. circuit diagram a map of a circuit, it shows parts and path of an electric circuit

25. If the switch is left open, what happens to the current?
The circuit does not make a complete loop, so the current cannot flow.

26. circuit diagram a map of a circuit, it shows parts and path of an
electric circuit
volt a measure of the electrical energy provided by an energy source
Ohms measure the amount of resistance to an electrical current.
amperes, also called amps. Current is measured by how much charge moves past a certain spot each second.
Volts are the measure of the electrical force provided by an energy source,
Amps measure how much current moves past a given spot each second in a circuit.
