Question
Which of the following devices is needed by a technician for protection against electrostatic discharge?A. MagnetB. Wrist strapC. Screw driverD. Surge protector
Solution
The correct answer is B. Wrist strap.
Here's why:
A. Magnet - Incorrect. Magnets can actually harm electronic devices by disrupting the magnetic fields within them.
B. Wrist strap - Correct. A wrist strap, also known as an anti-static wrist strap or ground bracelet, is used to prevent electrostatic discharge (ESD) by grounding the person wearing it. ESD can cause damage to sensitive electronic devices.
C. Screw driver - Incorrect. While a screwdriver is a useful tool for a technician, it does not provide protection against ESD.
D. Surge protector - Incorrect. A surge protector is used to protect electronic devices from voltage spikes, not ESD.
