Circuit Symbols and Components

This page presents a comprehensive collection of standardized electrical circuit symbols, essential for reading and creating circuit diagrams. Each symbol represents a specific component with unique functions in electrical circuits.

Definition: A switch can be represented in two states - open (circuit broken) or closed (circuit complete).

Highlight: Basic power sources are represented by cell and battery symbols, with the longer line indicating the positive terminal.

Example: Variable components like thermistors and LDRs change their resistance based on environmental conditions.

Vocabulary:

LED: Light Emitting Diode
LDR: Light Dependent Resistor
Ammeter: Measures current flow
Voltmeter: Measures potential difference

I love this app so much [...] I recommend Knowunity to everyone!!! I went from a C to an A with it :D

Stefan S, iOS User

The application is very simple and well designed. So far I have found what I was looking for :D

SuSSan, iOS User

Love this App ❤️, I use it basically all the time whenever I'm studying

Understanding Electrical Fundamentals

This page introduces core concepts of electrical circuits, focusing on the relationship between current, potential difference, and resistance. The content explains how these elements interact within electrical systems.

Definition: Current is defined as the flow of electrical charge through a circuit.

Definition: Potential difference, also known as voltage, acts as the driving force that pushes electrical charge around a circuit.

Highlight: The relationship between resistance and current is inverse - as resistance increases, current decreases.

Example: The formula Q = It (where Q is charge flow, I is current, and t is time) demonstrates how to calculate total charge flow in a circuit.

Vocabulary: The ohm (Ω) is the standard unit for measuring electrical resistance.
