What term describes a material that does NOT follow Ohm's law?
AConductive
BNonohmic
CInsulating
DResistive
Answer & Solution
Correct answer: B. Nonohmic
1. A material for which current is proportional to voltage is called ohmic.
2. A material for which this proportionality fails is given a specific name.
3. That name is stated directly to be nonohmic.
