Passage II

Physics students studied electrical current and resistance using the electrical circuit shown in Figure 1 below.

The students determined the electrical current, I, flowing through each of 3 devices—a resistor, a lightbulb, and a diode—for various voltages,

10. Based on Figure 3, the diode best conducted electricity when U for the diode equaled which of the following?

Answer and Explanation

Your Answer is

Correct Answer is J

Explanation

Best conducted electricity has the best conductivity, indicating that the resistance R is the smallest. So, looking at figure 3, it is found that the resistance at V=0.8 is the smallest among the four options
