How do substances get electrified explain?
Some atoms and molecules have a greater affinity for electrons than others and will become negatively charged by close contact in rubbing, leaving the other material positively charged. (See Figure 6.) Positive charge can similarly be induced by rubbing. Methods other than rubbing can also separate charges.
Why do like charges repel?
Whenever two like charges are placed near each other, they start exchanging a virtual photon amongst themselves, which transfers the momentum between them, and thus they appear to repel each other.
Is static electricity AC or DC?
Static electricity is the accumulation of electrical charges on the surface of a material, usually an insulator or non-conductor of electricity. It is called “static” because there is no current flowing, as there is in alternating current (AC) or direct current (DC) electricity.
