Comments
1
Revise electrostatics Define
current,Voltage and
Resitance
Can use Hewitt's video. Just the basics.
V,I and R should be carried over from Yr
10
2
Simple circuits
Predicting bulb brightness
Building circuits
Use simple parallel and series circuits to
get the basics established. This should
also include POE with hands on circuit
building. Most of this should be revision
from yr 10
3
Using meters
Units of V and I
Measuring I and V in series and parallel
4
Resistance
How does it relate to V and I? Really I
relates to V and R!
5
Resistance
What does it depend on?
6
Resistance in plarallel and
series circuits
Relevant equations. Lots of practice
questions
7
Modeling electric circuits
Use crocodile clips to model simple
circuits.
8
Ohm's law
9
Ohmic and Non Ohmic
devices
10
Houshold and car electricity
11
Ef f ects of electrical shock
12
Electric Pow er
13

Test
Practical: actual and/or model
Start with the V/I charateristic of a
lightbulb. Discuss v/I 's of diodes, LDR's
etc
Including Earth, fuses, circuit breakers.
Causes effects and treatments
P = VI (Important for DS 3.3)
Introduce kWh
