8. For a device in an electrical circuit that follows Ohm’s law, the ratio of the voltage across the device to the current flowing through the device is constant. Based on Figure 2, which of the 3 devices followed Ohm’s law throughout the interval from U = 0.00 V to U = 1.00 V?
Answer and Explanation
Your Answer is
Correct Answer is H
Explanation
From figure 2, it can be seen that only the U/I of the diode curve changes, so it does not comply with ohm's law, while the U/I of both resistor and light bulb are fixed values, which comply with ohm's law
