Study The I-V Characteristics of Non Ohmic Resistance

General Aim of Non Ohmic Resistance

Verify the nonlinear relation between current and voltage in a non Ohmic resistor.

Method

General method using Non-Ohmic resistance circuits.

Learning Objectives (ILOs)

Understanding the difference between the non Ohmic resistance and Ohmic resistance.

Set up an experiment to study the I-V characteristics of non Ohmic resistors.

Theoretical Background / Context

According to the type of material, its resistance may either obey Ohm’s law or not.

This can be explained by the behavior of these materials after connection in an electric circuit.

Non Ohmic resistance refers to the materials that are affected by the applied voltage via elevation in their temperature.

Hence, the value of the resistance is increased by increasing the voltage, which represents non Ohmic behavior.

What is non-Ohmic resistance? It is a characteristic property of certain non-Ohmic materials where the resistance changes with the applied voltage.

Principle Work of Non Ohmic Resistance

Direct measurement of the current vs the applied voltage on the non Ohmic resistance, and verify their relation does not obey Ohm’s law through the non Ohmic resistor equation.
