What are Ohmic & Non-Ohmic Conductors & Components

[@Enigma758]

But for non-ohmic devices, won't V=IR still hold at every point?

[@ElectronicsNotes]

This is a good point and yes it does, but the value of R changes with voltage. The definition of an ohmic conductor us one where the resistance is constant.

Thanks this helps a lot, I am writing a lab report on non-ohmic lightbulb and cannot make sense of the dependent and independent variable(I thought the independent variable should be current)

[@ElectronicsNotes]

Glad we were able to help.

i did'nt expect a youtube channel, i thought you guys only had a website

[@ElectronicsNotes]

Yes, I have a website and a youtube channel - I'm also active on X and LinkedIn as well.

Sir ur videos saved me so much time keep up the good work

[@ElectronicsNotes]

I am really glad you have found the videos useful Thanks very much for your comment.

Hi, I’m confused, so does resistance of ohmic condcutor change when temperature changes?

[@ElectronicsNotes]

Yes, even the resistance of a wire wound resistor will change. The changes are generally quite small and in many cases they won’t be noticed, especially over small temperature changes. However components like thermistors are designed to have a large resistance change with temperature so they can be used as sensors. Normally most resistors are designed to have a very small change of resistance with temperature.

hello Mr. I ask your permission to share your video in my channel to my student

[@ElectronicsNotes]

Can I suggest a link to the video as I don't want copies to appear around the Internet. Thanks.

[@التدريسيهايمانعبدالهاديفهد]

@@ElectronicsNotes thank you I have shared the link to my students

[@jayakumarir3526]

you reply like to every comment ?? damn that's cool i understood the concept thanks to you :)

[@ElectronicsNotes]

I try to reply to most, but I get quite a few these days with the channel growing so I can’t reply to everyone.

[@jllbddie]

thank you so much this is so helpful.

[@ElectronicsNotes]

I’m really glad it was useful. Thank for the comment. Please keep on watching our other videos.
