Studying Ohm's Law
The straight lines as shown in Figure 9 can be expressed as y = a
_{1}
+ a
_{2}
x. a
_{1}
and a
_{2}
are constant.
1.
What is the slope of the straight line?
 Figure 9 
2.
Is the slope constant along the line?
3.
Redo the experiment using a frequency of 0.1 Hz as shown in Figure 4. Does the slope still remain constant along the line?
4.
What is the physical meaning of the slope?
5.
Is the slope equal to the resistance (i.e. 10
) setting on the resistance box?
