Studying Ohm's Law

  The straight lines as shown in Figure 9 can be expressed as y = a1 + a2x. a1 and a2 are constant.

1. What is the slope of the straight line?

- Figure 9 -
2. Is the slope constant along the line?

3. Re-do 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?
