Miniatura What makes an object eletrically charged?: Explaining what makes an object electrically charged; the relation between the number of protons and electrons; explaining an equation which relates charge (q), number of protons, number of electrons and the fundamental charge (e).


Miniatura Electric charges - Exercises: Explaining the "q=(Np-Ne)e" equation more deeply and solving two exercises about electric charges.
