[amp_mcq option1=”AC outlet” option2=”Ground to bend” option3=”To another device” option4=”Chassis ground E. None of the above” correct=”option4″]
The correct answer is D. Chassis ground.
A chassis ground is a conductive path that connects the metal chassis of an electronic device to the earth. This helps to protect the user from electrical shock in the event of a fault.
Option A, an AC outlet, is not a good ground for a conductive work bench because it is not always connected to the earth. Option B, ground to bend, is not a good ground because it is not a reliable connection to the earth. Option C, to another device, is not a good ground because it does not provide a direct connection to the earth. Option E, none of the above, is not a good ground because it does not provide a safe and reliable connection to the earth.
A chassis ground is the best ground for a conductive work bench because it is a direct connection to the earth. This provides a safe and reliable path for electricity to flow in the event of a fault.
