Which of the following gives the resistance of a wire?

  1. R = IV
  2. R = I/2V
  3. R = V/I
  4. R = I/V
ಉತ್ತರ ತೋರಿಸು ಮತ್ತು ವಿವರಣೆ

ಉತ್ತರ: (C) R = V/I

ವಿವರಣೆ

By Ohm's law V = IR, so R = V/I.

  • (A) ತಪ್ಪು

    Wrong: IV is power, not resistance.

  • (B) ತಪ್ಪು

    Wrong: not a valid relation.

  • (C) ಸರಿ

    Correct: Ohm's law: R = V/I.

  • (D) ತಪ್ಪು

    Wrong: I/V is conductance.
