Definition: A small ring or circular band, often used in architecture or as a decorative element.

Example: The architect added an annulet to the top of the column for extra detail.

Definition: A ring-shaped structure or area, often found in nature or mathematics, that can refer to various forms such as growth rings in trees or the space between two circles.

Example: The annulus formed by the two circles was used to calculate the area between them.

Definition: A device that signals or indicates something, often used to show the source of calls or the status of electrical circuits.

Example: The hotel room had an annunciator that lit up when someone called the front desk.

Definition: Connected to or related to the anode, which is the positive electrode in an electrical device.

Example: The anodal stimulation improved the patient's recovery process.

Definition: In a manner that relates to or resembles an anode, which is the positive electrode in an electrical device.

Example: The current flowed anodally, indicating the direction of the positive charge.

Definition: A part of an electrical device where positive charge flows in, often used in batteries and electrochemical cells.

Example: In a battery, the anode is where the current enters the device.

Definition: Connected to the positive side of an electrical device where oxidation occurs.

Example: The anodic reaction in the battery helps to generate electricity.

Definition: To coat a metal, usually aluminum, with a protective layer through an electrochemical process.

Example: The manufacturer decided to anodise the aluminum parts to prevent corrosion.

Definition: The process of treating a metal surface to increase its resistance to corrosion and wear by forming a protective oxide layer.

Example: The anodization of aluminum helps to prevent rust and improve its appearance.

Definition: To apply a protective or decorative layer of oxide to a metal surface using an electrolytic process.

Example: The manufacturer decided to anodize the aluminum parts to improve their durability and appearance.
