I sure like all you videos and they are very helpful to me, thank you.
But I have a question about how charged insulators like for example a plastic ruler, can attract a conducter. I know that a conducter is neutral right? And the ruler is negatively charged/positive, but how is it the way they attract? Is it always that insulators attract conductors? In my science book it says that a negatively charged object repels negatively charged electrons. And positively charged object attracts negatively charged electrons.
Thanks! /Sara, ninth grade :)
I think that the ruler functions as a conductor not an insulator. The opposite charges are what draws materials together. Insulators work to draw electricity away from a conductor ex. electric wire.
Hope this helps. Godspeed.
