Basic Electronic Concepts

Voltage

Electrical pressure that pushes the electrons

Current

Number of electrons in motion in a current

Resistance

Electrical resistance is the opposition a material offers to the flow of electric current

Conductor

A material that allows electric charge (current) to flow through it easily

Insulator

A material that doesn't allow electric charge (current) to flow through it easily

Electron

Fundamental, negatively charged subatomic particle that orbits the nucleus of an atom, carrying electric current and determining chemical properties

Free electrons

An electron not bound to a specific atom, allowing it to move freely within a material, forming a 'sea' or 'cloud' of charge, especially in metals, which enables electrical conductivity

Volts

Unit for voltage

Amps

Measurement for current

Ohms

The standard unit of electrical resistance, measuring how much a material opposes electric current

Watts

Unit of power consumption

Circuit

A closed loop or path that allows something to travel around

Ohms Law

Describes the fundamental relationship in electrical circuits: Electrical current which is proportional to voltage and inversely proportional to resistance expressed as V=I⭑R
