what is electric charge

Electric charge is a basic property of matter that makes objects attract or repel each other in electric and magnetic fields.

Quick Scoop: Simple Idea

• Some particles, like electrons and protons, carry charge.

• Electrons have negative charge, protons have positive charge, and neutrons have no charge.

• If an object has more electrons than protons, it is negatively charged; if it has fewer, it is positively charged.

• Neutral objects have equal numbers of protons and electrons, so their charges balance out.

A handy way to think of it: charge is like a “label” on particles that tells them how strongly they push or pull on each other electrically.

Two Types: Positive and Negative

• There are two kinds of electric charge: positive and negative.

• Like charges repel (positive–positive or negative–negative), unlike charges attract (positive–negative).

• This push or pull is an electric force, and it acts through an electric field around the charged object.

Example: Rub a plastic comb on dry hair and small paper bits leap toward it—electrons moved from one material to the other, leaving one negatively charged and the other positively charged.

Where Electric Charge Comes From

• Charge arises because atoms contain protons (positive) and electrons (negative).

• When electrons move from one object to another, both objects become charged: one gains extra electrons (negative) and the other loses some (positive).

• Conductors (like metals) let electrons move easily; insulators (like plastic or glass) hold electrons tightly so they do not move much.

How We Measure Charge

• The amount of electric charge is measured in coulombs (symbol: C).

• A single electron carries a tiny charge of about −1.6×10−19-1.6\times 10^{-19}−1.6×10−19 coulombs; this is called the elementary charge.

• Any larger charge is basically some whole-number multiple of this smallest unit (for example, millions of electrons’ worth of charge).

Charge vs Electric Current

• Electric charge is “how much” electricity an object has; electric current is how fast that charge is flowing through something like a wire.

• When charges move steadily through a conductor, we call that an electric current (what powers circuits and devices).

One way to picture it: charge is like the amount of water in a tank, current is like the flow of water through a pipe.

TL;DR: Electric charge is a fundamental property of particles (like electrons and protons) that makes them attract or repel in electric and magnetic fields, comes in positive and negative types, and is measured in coulombs.
