Solution

The V-I curve that belongs to Ohmic components is the Straight line V-I curve.

Here's why:

  1. Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points. This means that if you were to increase the voltage, the current would increase proportionally, and vice versa.

  2. This relationship is represented graphically as a straight line on a Voltage-Current (V-I) graph. The slope of this line represents the resistance of the component.

  3. Non-linear, parabolic, and sinusoidal V-I curves represent non-ohmic components, where the current does not change proportionally with the voltage. These could be components like diodes, transistors, or other semiconductor devices.

So, the straight line V-I curve is the one that belongs to Ohmic components.
