Answer 2

Materials having a non-linear voltage-current relationship are called  B. Non-ohmic.

• Ohm's Law establishes a relation between potential difference and the current across a conductor.
• According to this law, when a graph is plotted against the potential difference V with the current I, it comes out to be a straight line.
• Devices that follow Ohm’s law are called ohmic devices while those that do not follow Ohm’s law are called non-ohmic devices.
• Resistor and wire are ohmic conductors whereas vacuum tubes and thermistors are non-ohmic.
• For non-ohmic conductors, the V-i graph is not a straight line.
