Can you electrify a metal rod by rubbing it while holding in your hand?

Yes, you can electrify a metal rod by rubbing it while holding it in your hand, but the effectiveness depends on the materials involved. Rubbing the rod with an insulating material can transfer electrons, causing the rod to become charged through the process of triboelectric charging. However, since metal is conductive, any charge that accumulates may quickly dissipate into your body or the surrounding environment, limiting the overall charge you can achieve.
