Question

why V I graph of non ohmic graph is opposite​

Answer 1

V - I graph for an ohmic material is a straight line passing through origin.

(ii) V-I graph for non ohmic material is a straight are non - linear curve, not passing through origin e.g. Junction c(i) the V - I graph of ohmic material is a straight line passing through origin. e.g. resistor made of margarine.(ii) V - I graph for non ...

Ohmic conductors are instruments which obey Ohm's law while non Ohmic conductors are ins
