Circuit Diagrams and HTML/CSS Fundamentals

Vocabulary flashcards covering electrical circuit diagram components, series/parallel connections, and key concepts of HTML documents and CSS styling.

Circuit Diagram

A graphical representation that simplifies an electrical circuit by presenting a depiction of its elements and their interconnections.

Battery (Circuit Symbol)

A component consisting of multiple electric cells connected in series, represented by cell symbols arranged so that the positive terminal of one cell connects to the negative terminal of the next.

Switch

A component represented by a line with a gap; bridging the gap indicates current flow (closed/on), while an open gap indicates current interruption (open/off).

Wire Joint

A point indicated by a dot or small solid circle where two or more wires intersect, signifying that they are electrically connected.

Wires Crossing Without Joining

Two wires crossing each other without a dot or circle at their intersection, indicating that they do not make electrical contact.

Electric Bulb

A lamp represented by a circle containing a cross, which signifies the filament or light-emitting portion of the bulb.

Resistor

A passive component represented by a zigzag line that is used to limit the flow of electric current in a circuit.

Variable Resistor

Also known as a rheostat or potentiometer, it is represented by a resistor symbol with an arrow or diagonal line indicating that its resistance value can be adjusted.

Inductor

A passive component consisting of several loops of wire, represented by a coil-shaped symbol, that stores energy in a magnetic field.

Fixed Capacitor

A non-polarized component represented by two parallel lines separated by a space, signifying its conductive plates.

Ammeter

A measuring instrument represented by a circle containing the letter 'A', used to measure electric current in a circuit.

Voltmeter

A measuring instrument represented by a circle containing the letter 'V', used to measure voltage or electrical potential difference.

Pictorial Diagram

A diagram that uses realistic pictures or images to represent components within a system.

Series Connection

A circuit arrangement where components are connected end-to-end to form a single continuous path for electric current to flow.

Node

The junction where two or more branches of an electrical circuit meet.

Branch

Any portion of a circuit containing two terminals connected to it, formed by one of the load components.

Parallel Connection

A circuit arrangement where all components are connected across each other's leads between the same set of electrically common points, causing the same voltage to be dropped across each component.

Declaration

A declaration placed at the top of an HTML document (before any tags) that informs web browsers about the document type to ensure proper page display.

HTML Attributes

Values specified in the start tag of an element, usually as name="value" pairs, providing additional information about the element.

href Attribute

An HTML attribute used within tags to specify the URL destination of a hyperlink.

src Attribute

An HTML attribute used within tags to specify the file path of the image to be embedded.

style Attribute

An HTML attribute used to apply inline CSS styles (such as color, font, or size) directly to an element.

lang Attribute

An HTML attribute declared within the tag to specify the language (and optional country code) of the web page.

title Attribute

An HTML attribute that defines extra information about an element, typically rendered as a tooltip when hovering over it.

XHTML (Extensible Hypertext Markup Language)

A stricter, XML-based version of HTML requiring mandatory document declarations, lowercase elements/attributes, quoted attribute values, and strict tag closing and nesting.

Cascading Style Sheets (CSS)

A language used to define layout, styling, and formatting rules for HTML web pages across different screen sizes and devices.

Cascading (in CSS)

The inheritance mechanism where styles applied to a parent element automatically pass down to all child elements contained within it unless explicitly overridden.

Inline CSS

A CSS application method where unique style rules are written directly inside an individual HTML element's style attribute.

Internal CSS

A CSS application method where styles for a single HTML page are defined inside a

External CSS

A CSS application method used to style multiple HTML pages by linking them to an external stylesheet file using the tag in the .
