### Part B - Current Density Comparison
**Task:**
Compare the current densities \( J_1 \) and \( J_2 \) in the two segments.
**Instructions:**
Match the words in the left column to the appropriate blanks in the sentence on the right.
**Options:**
- \( < \)
- \( = \)
- ————
- \( J \propto A \)
- \( J \) depends only on the current
- ————
- \( I_1 = I_2 \)
- \( A_1 < A_2 \)
**Sentence to Complete:**
\[ J_1 \gt J_2 \] because \([ \text{select option} ]\) and \[ J \propto \frac{1}{A} \].
**Diagram Explanation:**
- The diagram shows a cylinder with two segments labeled "1" and "2" with a current \( I_1 \) entering the first segment.
- This setup is meant to illustrate how current density varies across differently sized segments of a conductive material.
