Which materials are given as examples of ohmic conductors?
ACopper, aluminum, and silver
BRubber, glass, and wood
COnly pure silicon and germanium
DSalt water and human nerve tissue
Answer & Solution
Correct answer: A. Copper, aluminum, and silver
1. Ohmic materials are those for which Ohm's law holds over a wide range of voltage and current.
2. Good conductors named as examples of ohmic materials are copper, aluminum, and silver.
3. Rubber, glass, wood, salt water, and nerve tissue are not given in this list.
