A Tour of Electrical Components

A resistor is a passive electrical component with two terminals that implements electrical resistance as a circuit element, used for limiting or regulating the flow of electric current in a circuit

A capacitor is a device that stores electrical energy by accumulating electric charges. Unlike batteries which store charge chemically, capacitors store charge in an electric field.

An inductor is a coil of wire that stores energy in a magnetic field when electric current flows through it.

A battery is an energy source consisting of one or more electrochemical cells with terminals called an anode (-) and a cathode (+). These cells transform chemical energy into electrical energy and are used to power various devices and equipment

A diode is a low resistance two-terminal electronic component that conducts current primarily in one direction.

A transistor is a semiconductor device used to amplify or switch electrical signals and power.

A switch is a small control for an electrical device that you use to turn the flow of current on or off.

A relay is an electrically operated switch. It consists of a set of input terminals for one or more control signals and a set of operating contact terminals. Sending voltage to the signal terminal will turn the switch on.

An integrated circuit, also known as a microchip, chip, or IC, is a small electronic device made up of multiple interconnected electronic components such as transistors, resistors, and capacitors. ICs provide pre-built circuits for performing common functions.

Meters are devices that can be used to measure various parts of an electric circuit.
