Vedclass · Answer

(C) Ohmic devices obey Ohm's law,which states that the current $I$ flowing through a conductor is directly proportional to the potential difference $V$ applied across its ends,provided the physical conditions (like temperature) remain constant.This is expressed as $V = IR$,where $R$ is the resistance of the device.Since $R$ is constant for an Ohmic device,we have $I = (1/R)V$.This equation represents a straight line passing through the origin $(0,0)$ with a slope of $1/R$.Among the given options,the graph that shows a straight line passing through the origin is Graph $C$.

Of the following graphs,the one that correctly represents the $I-V$ characteristics of an 'Ohmic device' is:
