To determine which device does not obey Ohm's law, we need to analyze the relationship between the potential difference (V) and the current (I) for both devices. According to Ohm's law, the ratio \( \frac{V}{I} \) (which represents resistance, R) should remain constant for a device that obeys Ohm's law. ### Step-by-Step Solution: 1. **List the Data**: - Device 1: - \( V_1 = 2 \, \text{V}, I_1 = 4.5 \, \text{A} \) - \( V_2 = 3 \, \text{V}, I_2 = 6.75 \, \text{A} \) ...
