Connecting Circuits
LEARNING TARGET: I can describe how energy is transferred through different circuits and how it is transformed through different devices.
CH Q
How is energy transferred and transformed in a electrical circuit?
VOCAB:
Circuit; parallel circuit; series circuit

3. complete path for electrons to follow
Circuit
parallel circuit
series circuit
complete path for electrons to follow
where “appliances” have their own independent path to follow
where “appliances” are one after another and depend on each other

7. This is an example of a __________ circuit. series
POST DISCUSISON
This is an example of a __________ circuit.
series
2. Describe all you can about how this circuit works.
This circuit works because…
… the path is complete going through each light in turn (in series)
If one light went out then…
ALL would go out (circuit broken)

8. POST DISCUSISON
This is an example of a __________ circuit.
parallel
2. Describe all you can about how this circuit works.
This circuit works because…
each light has its own independent path to use
If one light went out then…
the others would work
(each has its own complete circuit to use)

9. each light is part of continuing the circuit (series) if one burns out (filament breaks) – circuit is broken

10. Explain why this is funny?
What is the science pun behind it?

11. complete circuits, energy transfers and transforms
more bulbs =
less bright
(series "shares")
all lights full bright
complete circuits, energy transfers and transforms
one bulb out,
all go out
one bulb out, others lit
describe series 1st, then parallel – finally common to both

12. ANALYSIS
- Discuss and answer Q 2 & 3 on pg. D 79
ANS CH Q
How is energy transferred and transformed in a electrical circuit? A:
transferred through conductive wires and appliances
transformed by wires into heat and by appliances in ways needed to do work
(heat, light, sound, etc.)
