Answer
| Ohmic resistor | Non-ohmic resistor |
|---|---|
| It obeys the Ohm's law i.e., is constant for all values of V and I. | It does not obey the Ohm's law i.e., is not same for all values of V and I. |
| The graph for potential difference V versus current I is a straight line passing through the origin. | The graph for potential difference V versus current I is not a straight line, but is a curve which may not pass through the origin. |
