Electricity
Model
2b.1
In this model, you can plot a
graph of V against
I in a circuit with a resistance R (Ohm’s Law). You can enter values of
V in the first column, and the computer will calculate the value of I
in
the second column and plot points on a graph so that you can see the
pattern.
You can also change the value of the resistance.
Model
2b.2
This model is similar to Model
2b.1, which plots
a graph of V against I in a circuit. In this model, there are two
columns
for different values of the resistance so that you can compare the
effects
of changing the resistance. The graph plots two sets of points with
different
colours corresponding to the two resistances.
