The video revisits the concept of electricity, explaining its two main types: static and current. Static electricity involves charge accumulation, demonstrated by a plastic comb attracting paper pieces. Current electricity involves charge flow through wires, generated chemically in batteries or mechanically in generators. The video sets the stage for deeper exploration of electric currents.

What happens when you bring a plastic comb close to small paper pieces after combing your hair?

• The comb loses its charge.

• The comb changes color.

• The paper pieces are attracted to the comb.
