Electrostatics — three ways to learn it.

Charge from friction, Coulomb's inverse-square law, the electric field and its field-line maps, electric flux and Gauss's law, electric potential, and the first idea of capacitance. Read the full lecture, watch every concept come alive with everyday objects, then run the virtual experiment. Pick any door — they all teach the same chapter.

Lecture & walkthrough

The complete written lesson — charge and charging by friction (q = ne), conductors vs insulators and earthing, Coulomb's law F = kq₁q₂/r², the electric field E = F/q, field lines, electric flux and Gauss's law, electric potential V = kQ/r, and the first look at capacitance.

Interactive lecture

As you scroll, a live animated panel plays out every idea with an object you already know — a balloon rubbed on hair, a comb lifting paper, charged pith balls feeling Coulomb's force, field lines mapping the field, and a lightning discharge.

Run the Coulomb's-law experiment on a safe, virtual bench: vary the charges and the separation, read the force off the meter, and plot F against 1/r² to confirm the inverse-square law for yourself.
