Coaxial cables transmit RF signals with low loss through copper core and shielding. Core consists of copper wire, dielectric insulator, braided shield, and jacket. Shielding prevents signal interference and maintains consistent distance between core and shield
Fabrics are produced using specific yarns and various techniques. Fabric names typically indicate the fiber used in production. Each fabric has unique names based on texture, design, and origin
Drill bits are essential tools for making holes and driving screws in various materials. Bits are made of steel, cobalt, carbide, or other metals. Power (battery or electric) controls the rotation of the rotary tool
HDMI is a standard interface for digital audio and video transmission since 2003. Features 19 pins in 13.9mm × 4.45mm rectangular connector. Supports latest HDMI standards up to 48Gbps bandwidth. Widely compatible but bulky for portable devices
Patch cables connect electronic devices for signal routing. They are stranded copper cables with connectors at both ends. Length ranges from 3 inches to 50 meters for snake cables
Conductor allows electric current flow in one or more directions. Current flows through momentum transfer between mobile charge carriers. Metals are ideal conductors due to delocalized electron sea
