Identify VI graph for ohmic and non ohmic materials
Answers
VI graph for Ohmic and Non-ohmic Materials:
- V-I graph of ohmic material is a straight line passing through the origin. e.g. wire, incandescent light bulb, electric stove heating element.
- V-I graph for non-ohmic material is a straight are non - linear curve, not passing through origin e.g. music players, computers, telephones, etc
Explanation:
The main difference between an Ohmic and a non-Ohmic conductor is whether they adhere to Ohm's law. An Ohmic conductor would have a straight connection between the current and the voltage. With non-Ohmic conductors, the relationship isn't direct.
Other carries in a manner that isn't portrayed by Ohm's law, (for example the obstruction isn't steady, but changes in a way that relies upon the voltage across it.) The gadget is supposed to be non-Ohmic. For this situation, V versus I diagram is anything but a straight line yet has some surprising shape.
Example of ohmic conductor: Copper wire, metal, etc.
Example of non-ohmic conductor: Diode, semiconductor, filament bulb, etc.
