Some theoretical questions that got me confused during physics lecture today.
bringing a conducting balloon to a negatively charged rod close will allow the conducting balloon have positive charges closer to the rod. when the rod touches the conducting balloon, why is it that the rod(dielectric) transfers its -ve charges to the conductor instead of other way around since it's harder for charges to move inside a dielectric.
How exactly does charge by friction work? How I recognize it is that the stronger insulator will absorb electrons from the weaker insulator leaving one positively charged and one negatively charged?
When you charge a balloon and stick it to a wall, after sometime the balloon slowly loses its charged state. But balloon is a dielectric(rubber) so how does it lose the charge? I'm assuming friction from rubbing against air slowly picks away at the charged electrons? Some clearer explanation would be great!
