Basics

Electrons, Protons

Baiscs

positive electrical charge; electrons, which carry a negative charge; and neutrons, which carry no charge.

Conductors

Basics

a material which electricity, heat or sound can flow through.

Insulators

Basics

a material which is used to reduce the conduction of electricity, heat or sound.

Electric Circuits

Basics

a path in which electrons from a voltage or current source flow.

Calculation

Voltage

Baiscs

Voltage is what makes electric charges move.

Current

Basics

Electron moves

Resistance

Basics

a measure of the difficulty of passing an electric current through a substance.

Ohm's Law

Basics

Ohm's law says that in an electrical circuit, the current passing through a resistor between two points, is related to the voltage difference between the two points, and are related to the electrical resistance between the two points.

Circuit Types

Series Circuits

Baiscs

One

Parallel Circuits

Basics

Multiple

Combination Circuits

Basics

Complex

Components

Battery

Baiscs

A battery converts chemical energy into electrical energy by a chemical reaction.

Fuses

Basics

A fuse is a device that shuts off the power to an electrical circuit when too much electric current flows through it.

Capacitors, Calculus

Basics

A capacitor is an electronic device that stores electric energy. It is similar to a battery, but can be smaller, lightweight and a capacitor charges or discharges much quicker.

Electromagnetism

Basics

Electromagnetism is the study of the electromagnetic force, one of the four fundamental forces of nature. The electromagnetic force pushes or pulls anything that has an electric charge, like electrons and protons.

Resistors

Basics

A resistor limits the electric current that flows through a circuit.
