Jul 7, 2025 · Electric circuits are classified in several ways. A direct-current circuit carries current that flows only in one direction. An alternating-current circuit carries current that pulsates back and forth many times each second, as in most household circuits.

The basic components of analog circuits are wires, resistors, capacitors, inductors, diodes, and transistors. Analog circuits are very commonly represented in schematic diagrams, in which wires are shown as lines, and each component has a unique symbol.

Welcome to circuits 101! One of the first things you'll encounter when learning about electronics is the concept of a circuit. This tutorial will explain what a circuit is, as well as discuss voltage in further detail.

Electric circuits are composed of wires and other components -- like light bulbs, transistors, computer chips and motors. Wires, made of metals called conductors that have a low resistance to current, connect the components. Copper and aluminum are the most common conductors.

The flow of charge through electric circuits is discussed in detail. The variables which cause and hinder the rate of charge flow are explained and the mathematical application of electrical principles to series, parallel and combination circuits is presented.

Aug 27, 2024 · Circuits are interconnected pathways that allow the flow of electric current, typically consisting of components like resistors, capacitors, inductors, and transistors. These elements are connected by conductive wires or traces through which electrons travel, creating a complete path for the current.

Sep 18, 2024 · What is an Electric Circuit? An Electric Circuit is a closed path for transmitting an electric current through the medium of electrical and magnetic fields. The flow of electrons across the loop constitutes the electric current. Electrons enter the circuit through the ‘Source’ which can be a battery or a generator.

A complete path, typically through conductors such as wires and through circuit elements, is called an electric circuit.

Introduction to circuits, including several methods for analyzing circuits (Kirchhoff’s current and voltage laws, node voltages, and loop currents) and common patterns that simplify analysis. These videos have been developed for OCW Scholar, and are designed to …
