Answer: D. Passive, bilateral and linear elements
Ohm's law is true for passive, bilateral and linear elements.
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.
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.
