Answer:
Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons. A van de Graaff generator produces a negative charge on its dome, so it tends to give up electrons. Human hands are positively charged, so they tend to accept electrons.
Explanation:
In triboelectric nanogenerators, charge is transferred between two dielectric materials that have distinctly different triboelectric characteristics with one easy to gain electrons and the other one easy to lose electrons. Please explain how the charge transfer takes place? If possible please explain it in terms of valence electrons.
