2. Antistatic device - Wikipedia

   en.wikipedia.org/wiki/Antistatic_device

   An antistatic wrist strap, ESD wrist strap, or ground bracelet is an antistatic device used to safely ground a person working on very sensitive electronic equipment, to prevent the buildup of static electricity on their body, which can result in ESD.

3. Ground (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_(electricity)

   Strictly speaking, the terms grounding or earthing are meant to refer to an electrical connection to ground/earth. Bonding is the practice of intentionally electrically connecting metallic items not designed to carry electricity. This brings all the bonded items to the same electrical potential as a protection from electrical shock.

4. Electrostatic-sensitive device - Wikipedia

   When working with them, a technician will often use a grounding mat or other grounding tool to keep from damaging the equipment. A technician may also wear antistatic garments or an antistatic wrist strap. [3] There are several kinds of ESD protective materials: [4] Conductive: Materials with an electrical resistance between 1kΩ and 1MΩ

5. Ground loop (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_loop_(electricity)

   The ground loop still exists, but the two sides of the loop are close together, so stray magnetic fields induce equal currents in both sides, which cancel out. Break in the shield Create a break in the signal cable shield conductor. [5] The break should be at the load end. This is often called ground lifting. It is the simplest solution; it ...

6. Electrostatic discharge - Wikipedia

   en.wikipedia.org/wiki/Electrostatic_discharge

   Electronics manufacturers therefore establish electrostatic protective areas free of static, using measures to prevent charging, such as avoiding highly charging materials and measures to remove static such as grounding human workers, providing antistatic devices, and controlling humidity.

7. Pull-up resistor - Wikipedia

   en.wikipedia.org/wiki/Pull-up_resistor

   When the switch is open the voltage of the gate input is pulled up to the level of Vin. When the switch is closed, the input voltage at the gate goes to ground. In electronic logic circuits, a pull-up resistor (PU) or pull-down resistor (PD) is a resistor used to ensure a known state for a signal. [1]
