Throughout the voltage divider experiment a student observes the current never changes as long as the power supply voltage is never changed. They would like to make a plot to determine if the potentiometer is linear with respect to wiper position. Which of the following plots allows for that determination by giving a straight line if the device is linear? All of these plots will give a straight line if the potentiometer is linear. l2 O A plot of V₁ - V₂ (vertical axis) vs (horizontal axis). l₁ O A plot of 2 (vertical axis) vs (horizontal axis). l₁ O A plot of V₁ + V₂ (vertical axis) vs l2 (horizontal axis).

Expert Solution
Step 1
A plot of V₁ - V2 (vertical axis) vs (horizontal axis) allows for the determination if the potentiometer is linear with respect to wiper position, as it represents the voltage drop across the potentiometer. If the potentiometer is linear, the plot will be a straight line with a negative slope, indicating a constant resistance. If the potentiometer is not linear, the plot will be a curved line
