Ohm's LawEasyQuestion 31603

Question

Ohm's law states that current through a conductor is proportional to potential difference, provided:
  1. A
    Temperature varies
  2. B
    Physical conditions remain constant
    Correct
  3. C
    Cross-section changes
  4. D
    Material changes

Correct answer

Physical conditions remain constant

Explanation

Ohm's law (V = IR) holds when temperature and other physical conditions are kept constant. R is then a constant (material property).
