Which bonding method utilizes rigid plates to connect two or more components of an electrical system?

The correct answer pertains to terminal bars, which are designed specifically to provide a robust and reliable connection between multiple components in an electrical system. Terminal bars consist of conductive metal plates that allow various wires and conductors to be securely attached, thereby facilitating efficiency in electrical distribution and reducing the risk of connection failures. These rigid plates can accommodate multiple connections, making them ideal for applications requiring a stable and organized wiring layout.

In contrast, exothermic welding relies on a chemical reaction to create a metallurgical bond between conductive materials, making it more suitable for permanent connections rather than connecting multiple components in a modular fashion. Screw type fasteners are commonly used in mechanical assemblies but do not inherently provide electrical connections on their own; rather, they simply hold components in place. Jumper wires, while functional for connecting components, are typically flexible and used for temporary connections rather than the type of stable and secure connection that terminal bars provide.
