Non Ohmic Resistance is a key concept in electricity that demonstrates how certain materials exhibit a nonlinear relationship between current and voltage. Unlike Ohmic conductors, non-Ohmic resistors experience changes in resistance as temperature rises with increasing applied voltage. Through this experiment, students investigate the I-V characteristics of a non-Ohmic resistor, compare its behavior with Ohmic resistance, and understand why it does not follow Ohm's law. By collecting and analyzing experimental data, learners gain practical insights into electrical conductivity, resistance variation, and the principles governing non-Ohmic materials in real-world electrical and electronic applications.
