If you don't have a field kit handy, touching which components in the chassis will give you zero potential for ESD?

• A. Motherboard and CPU
• B. Power Supply Case and Bare metal on the inside of the chassis
• C. Graphic card and RAM
• D. Hard Drive and SSD

Answer: (B)

Touching the power supply case and bare metal on the inside of the chassis provides zero potential for electrostatic discharge (ESD) because these components are typically grounded. Grounding helps dissipate any static electricity that may have accumulated on your body or clothing at the moment of contact, thus preventing the buildup of charge that could damage sensitive computer components. In a computer chassis, both the power supply unit (PSU) casing and the bare metal surfaces are connected to ground. This connection allows any static charge to safely drain away, protecting other critical components inside the system from potential ESD damage. The other components mentioned—motherboard, CPU, graphic card, RAM, hard drive, and SSD—are all sensitive to ESD and touching them without proper precautions can lead to damage, making them riskier to handle when you don't have a field kit available.
