What tool can protect computer components from ESD?

• A. Surge Protector
• B. Antistatic Wrist Strap
• C. Cooling Pad
• D. Power Supply Tester

Answer: (B)

An antistatic wrist strap is designed specifically for protecting sensitive electronic components from electrostatic discharge (ESD). When working on computer hardware or handling electronic parts, static electricity can build up on your body and, when discharged, can cause significant damage to circuits and components. Wearing an antistatic wrist strap ensures that any static buildup is safely dissipated to the ground, effectively preventing harmful ESD.

In contrast, while a surge protector is essential for safeguarding equipment from voltage spikes, it does not address static electricity. Cooling pads are primarily used to manage the temperature of laptops and other devices but do not provide ESD protection. A power supply tester helps verify the functionality of a power supply unit but, again, is not related to controlling static electricity. Therefore, the antistatic wrist strap is the most suitable tool for this specific purpose.
