I V Graph | MCQs

Explanation

For non-Ohmic materials, the current-voltage (I-V) relationship does not follow Ohm's law, which states that current is directly proportional to voltage (resulting in a linear I-V graph).

In non-Ohmic materials, the relationship between current and voltage is non-linear, and the I-V graph is typically curved.

Examples of non-Ohmic materials include diodes and transistors, where the resistance changes with voltage or current.
