Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.

Question

**Determining Electrical Conductivity of a New Material**

You've been tasked with assessing whether a newly developed material is ohmic and measuring its electrical conductivity. A sample with dimensions 0.50 mm x 1.0 mm x 45 mm is tested by connecting its ends to a power supply. The current is measured across various potential differences, resulting in the following data:

| Voltage ΔV (V) | Current I (A) |
|-----------------|---------------|
| 0.200 | 0.47 |
| 0.400 | 1.06 |
| 0.600 | 1.53 |
| 0.800 | 1.97 |

**Part A: Graphing to Determine Ohmicity and Conductivity**

The objective is to determine if the material adheres to Ohm's Law and to calculate its conductivity (σ). To achieve a straight-line graph that reveals these properties, follow these steps:

- **Select Variables for Graphing:**
- Horizontal axis: Choose the independent variable.
- Vertical axis: Choose the dependent variable.

Available options:
- \( \frac{1}{\Delta V} \)
- \( (\Delta V)^2 \)
- \( \Delta V \)
- \( I \)

*Tip: For a material to be ohmic, the current (I) should be directly proportional to the voltage (ΔV), resulting in a linear relationship.*

Once the appropriate variables are selected, plot the data to identify the material’s behavior and conductivity characteristics.
