Ohm's Law Is True For

By Aina Parasher|Updated : July 8th, 2022

Ohm's law is true for-

  1. Passive, bilateral and non-linear elements
  2. Active, bilateral and linear elements
  3. Passive and unilateral elements
  4. Passive, bilateral and linear elements

Answer: D. Passive, bilateral and linear elements

Ohm's law is true for passive, bilateral and linear elements.

Solution

Ohm’s law states that the electric current is flowing through a conductor proportional to the potential drop across the element at a constant temperature.

i∝v

The current and voltage characteristics are linear for ohms law elements. The characteristics are in Q1 and Q3. This shows that,

  • For reversal directions of voltage, the current direction also gets reversed. i.e., the element must be bilateral.
  • The current and voltage are proportional and pass through the origin. It indicates that the element is linear.
  • Power consumption of an element is positive. i.e., the voltage and current product is positive in both the quadrant. It indicates that the element is passive. 
  • Example: R, L and C with zero initial conditions.

Ohm's law is true for linear, bilateral, and passive elements.
