Choke

For other uses, see Choke (disambiguation).

Choke can refer to several different concepts across various fields, including mechanical engineering, sports, and medicine. This article provides an overview of the different meanings and uses of the term "choke."

Mechanical Engineering

In mechanical engineering, a choke is a device used to restrict the flow of a fluid, such as air or fuel, in an engine. It is commonly found in internal combustion engines, where it helps to regulate the air-fuel mixture, especially during cold starts. The choke can be either manual or automatic, depending on the design of the engine.

Sports

In the context of sports, to choke means to fail to perform at a crucial moment, often due to pressure or anxiety. This term is frequently used in competitive sports such as basketball, tennis, and golf. A well-known example is when a player or team is leading comfortably but then loses the advantage due to nervousness or loss of focus.

Medicine

In medicine, choking refers to the obstruction of the airway, which can prevent breathing and lead to a medical emergency. Choking can be caused by food, small objects, or other foreign bodies becoming lodged in the throat or trachea. Immediate intervention, such as the Heimlich maneuver, is often required to clear the obstruction and restore normal breathing.

Electronics

In electronics, a choke is a type of inductor used to block higher-frequency alternating current (AC) in an electrical circuit while allowing lower-frequency or direct current (DC) to pass. Chokes are commonly used in power supplies and radio frequency (RF) applications to filter out unwanted signals.
