Question
Give two difference between an ohmic and non-ohmic resistor.
Distinguish Between
Solution
| Ohmic resistor | Non-ohmic resistor | |
| 1. |
V/I remains constant regardless of the value of V or I, as it follows Ohm's law. |
V/I is not constant and does not remain the same for all values of V or I since it does not follow Ohm's law. |
| 2. | A straight line represents the relationship between current I and projected V. | A straight line does not appear on the graph that plots current I against potential difference. |
