Question

to prevent esd when replacing internal computer components, you attach an anti - static wrist strap to your wrist. where should the other end be fastened? (select two.)
anti - static mat
ground wire on the power supply
ground wire on the wall power outlet
metal area on the computer case
screw on the wall power outlet

Explanation:

To prevent Electro - Static Discharge (ESD) when working on computer components, the other end of an anti - static wrist strap should be connected to a grounded metal part. A ground wire on the power supply, ground wire on the wall power outlet, and metal area on the computer case are all suitable grounding points as they provide a path for the static electricity to flow safely away. An anti - static mat is mainly for placing components on and not for connecting the wrist strap. Screws on the wall power outlet are not proper grounding points for an anti - static wrist strap.

Answer:

• B. Ground wire on the power supply
• C. Ground wire on the wall power outlet
• D. Metal area on the computer case
