What is the recommended resistance value range to ensure proper grounding when using an antistatic strap to perform work on electrical components?
The correct answer is B. Between 1 and 10 megaohms. The ideal resistance range for ESD wrist straps is between 1 and 10 megaohms. This range is sufficient to safely discharge static electricity from the technician to ground, while not allowing an abrupt discharge that could damage sensitive electronic components. Values below 1…

Explanation
The ideal resistance range for ESD wrist straps is between 1 and 10 megaohms. This range is sufficient to safely discharge static electricity from the technician to ground, while not allowing an abrupt discharge that could damage sensitive electronic components. Values below 1 megaohm may result in a rapid discharge, risking damage. Values above 10 megaohms may not discharge static efficiently enough.
