Q. Are ebonite rods beneficial or harmful?

Answer

An ebonite rod has a negative charge, whereas a fur pelt has a positive one. The electrons in the fur are transferred to the ebonite rod when rubbing the two together. The lack of electrons has caused the fur to become positively charged. The ebonite rod, on the other hand, is negatively charged because it possesses an overabundance of electrons. A positive electrical charge is applied to the fur in the first scenario. It's important to remember that during positive (and negative) electrification, it's the electrons, not the protons, that are exchanged. This is why generating charges by rubbing the copper rod with a flannel causes current to travel counterclockwise around the rod before moving to the hand.
