Question

The formula $V=IR$ is applicable to :

• A. Ohmic conductors only
• B. Non ohmic conductors only
• C. Both Ohmic & Non ohmic conductors
• D. Neither ohmic nor non ohmic conductors

Answer 1

Answer: (A)

Ohmic conductors only

According to Ohm's law $V\propto I$ or $V=IR$, Where R= Constant for all temperatures.

For Ohmic conductors Value of $R$ is constant and for Non-ohmic its value can change.

Hence, Option A
