Ring and fork terminals are types of electrical connectors used in wiring applications. A ring terminal has a circular-shaped end that encircles a screw or stud, providing a secure connection. Fork terminals, on the other hand, have a forked shape that can be slid onto a screw or stud without completely removing it. Both terminals are used in automotive, industrial and household electrical installations to create reliable connections and facilitate easy attachment to screws or studs. They are available in various sizes to accommodate different wire gauges.
