From the graph between current (I) and voltage (V) is shown. Identify the portion corresponding to negative resistance
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
For the negative resistance, when we increase the voltage, the current will decrease. Therefore from the graph, we find that the current in CD is decreased when voltage is increased.
