Crocodile clips, also known as alligator clips, are spring-loaded metal clips with serrated jaws. They resemble the toothed jaws of a crocodile or alligator, hence the name. These clips serve various purposes in electrical and non-electrical applications:

1. Electrical Connections:

   • Crocodile clips are commonly used to create temporary electrical connections. They can connect two wires or attach a lead directly to a device.
   • In laboratories and experimental circuits, they prove incredibly useful for testing and demonstrations.
   • Different materials are used for crocodile clips:
     • Stainless steel: Durable and corrosion-resistant, but challenging to solder.
     • Nickel-plated steel: Offers excellent corrosion resistance.
     • Gold-plated steel: Ideal for low resistance and high conductivity, but wears easily.
     • Copper: Suited for excellent electrical conduction.

2. Non-Electrical Uses:

   • Identification: Crocodile clips hold identification badges onto lanyards.
   • Assembly: Hobbyists use them to hold things together during gluing or modeling.
   • Dentistry: They find application in dentistry bibs.

3. Automotive Clips:

   • Larger crocodile clips, sometimes called plier clips, are used in the automotive industry.
   • These clips, made from low-resistance materials like solid copper, serve purposes such as jumper cables, battery chargers, and welding applications.
