Question
**Educational Resource: Current, Current Density, and Electric Field in an Aluminum Wire**

An aluminum wire consists of three segments with varying diameters, as displayed in the accompanying figure. The current in the top segment is given as 7.0 A.

### Figure Description:
The diagram shows a vertical aluminum wire divided into three cylindrical segments. The top and bottom segments have a diameter of 2.0 mm, while the middle segment has a smaller diameter of 1.0 mm. The current \( I \) flows downward through the wire.

### Part A
For each of these three segments, we need to find the current \( I \).

- **Task:** Express your answers using two significant figures separated by commas.
- **Input Box:** \( I_{\text{top}}, I_{\text{mid}}, I_{\text{bot}} = \) ___ A
- **Action:** Submit your response.

### Part B
For each of these three segments, find the current density \( J \).

- **Task:** Express your answers using two significant figures separated by commas.
- **Input Box:** \( J_{\text{top}}, J_{\text{mid}}, J_{\text{bot}} = \) ___ A/m²
- **Action:** Submit your response.

### Part C
For each of these segments, find the electric field \( E \).

- **Task:** Express your answers using two significant figures separated by commas.
- **Input Box:** \( E_{\text{top}}, E_{\text{mid}}, E_{\text{bot}} = \) ___ V/m
- **Action:** Submit your response.

In each section, you can also request additional hints if needed to solve the problem.

**Note:** When completing the calculations, ensure that all steps adhere to the principles of physics, considering areas and resistances in circular segments of the wire for accurate computation of current density and electric fields.
