Electrical Fundamentals and Circuit Basics
This page introduces core concepts in electricity and circuit theory, providing a foundation for understanding electrical circuits.
The document begins by defining electrical resistance as the opposition to the flow of electricity, measured in ohms Ω. It then explains electrical current as the measure of electron flow, measured in amperes A, and how it depends on voltage and resistance.
Voltage is described as the force causing current to flow, measured in volts V, and also referred to as potential difference. The page also covers conductors and insulators, explaining their roles in electrical systems.
Vocabulary: Ohm Ω - The unit of electrical resistance.
Definition: Electrical current is the measure of the flow of electrons or electricity in a circuit.
The concept of static electricity is introduced, along with static discharge and static charge. The document explains how objects become charged through gaining or losing electrons.
Highlight: Static discharge occurs when electrons move toward equilibrium, as objects don't hold static charge indefinitely.
The page concludes with an introduction to series and parallel circuits, outlining their basic characteristics and behaviors.
Example: In a series circuit, multiple light bulbs will become dimmer as the current reduces, while in a parallel circuit, they maintain the same brightness.
