What component is described as a grounding path created by driving an electrode into the earth?

• A. Bonding strap
• B. Driven electrode
• C. Ground loop
• D. Lightning rod

Answer: (B)

The concept being tested is how a grounding path to earth is established by physically inserting an electrode into the soil. A driven electrode refers to a grounding electrode that is installed by driving it into the ground, typically forming the external grounding path for a electrical system. This is the standard way to create a low-impedance connection to earth, often using a ground rod made of copper or steel and connected to the service equipment with a grounding conductor. The other terms describe different ideas: a bonding strap is just a conductor that ties metal parts together to keep them at the same potential; a ground loop is an unintended circulating current path that can cause noise or stray currents; a lightning rod is part of protection against lightning and provides a grounding path, but the common description of a grounding path created by driving an electrode into the earth specifically defines a driven electrode.
