For a metallic wire, the ratio of voltage to corresponding current is

Options

  1. Aindependent of temperature
  2. Bincreases with rise in temperature
  3. Cincreases or decreases with rise in temperature depending upon the nature of the metal
  4. Ddecreases with rise in temperature

Correct answer

B. increases with rise in temperature

Step-by-step solution

∵ V i = R ∵ R = R 0 1 + ∝ ∆ T If temperature increases, resistance also increases. So, does V i .
