Question

Which of the following is an example of a Non-Ohmic material?

विकल्प

• Metallic wire

• Resistor

• Diode

• Copper bus bar

Answer 1

Non-Ohmic materials, such as diodes and thermistors, exhibit a non-linear V-I relation and variable resistance. Ohmic conductors, like metallic wires and resistors, show linear V-I relations with constant resistance under fixed conditions.
