A wrist grounding strap is used to prevent electrostatic discharge when handling computer components. Just like a shock when walking on carpet can carry several thousand volts, it destroys computer components. In more detail, it is a wire leading from a technician's body (a wrist band with metal contact to the skin) to earth ground, with a high (1 megohm) resistance in it. This slowly discharges any static electricity that is built up on the body, to avoid discharging it into an electronic component. An electrostatic discharge (ESD) mat with similar connection to ground is also used to keep the electronic components at earth ground potential.

What does wrist grounding strap contain?
resistors
Wrist strap to eliminate static charges?
A wrist strap is a device worn on a person's wrist that is connected to a grounding point. It helps to prevent static charges from building up on the body by providing a path for the charge to flow to ground. This can help protect sensitive electronics from damage caused by electrostatic discharge.
What is the purpose of the wrist grounding straps?
Wrist grounding straps are used to prevent the buildup of electrostatic discharge (ESD) when handling sensitive electronic components. By connecting the strap to a grounded surface, it allows the static electricity to safely dissipate, protecting the components from potential damage.
What computer components should you not touch while wearing antistatic wrist strap?
I'm not aware of any component you cannot touch. As long as the power is off and you are grounded properly. You would have to touch any component part in order to replace or upgrade it. When using a Antistatic wrist strap you should always male sure it makes contact your skin properly, if the strap has a crocodile clip at the end make sure it is attached to a suitable grounding point. You can clip it to the PC chassis but make sure the power is off at the wall socket but the plug is left inserted, if you unplug the PC completely there is no grounding. Saying all this grounding yourself is a bit over rated. I rarely use a grounding wrist strap and have never had an incident.
What is the length of the wrist strap?
Length of wrist strap/Band circumference = 7 inches.
How does a technician discharge static build up?
A; By wearing a wrist strap connected to chassis and grounding the chassis to earth ground
When should a technician avoid wearing an antistatic wrist strap?
A technician should avoid wearing an antistatic wrist strap when working on equipment that is powered on, as the strap can create a grounding path that might short out components or cause electrical shocks. Additionally, if the technician is working in a highly sensitive environment where static discharge could interfere with the operation of delicate devices, it might be prudent to remove the strap. Lastly, if the technician is in a non-static-sensitive environment, the strap may be unnecessary.
To prevent damage to your computer how do you safely discharge static electricity before working on it?
you must be grounded via a grounding strap, which consists of a condective strap around your wrist (contacting your skin) a resister (usually about 1 megaohm) and a connection to earth ground.
What is the first step when working on the inside of a computer?
PRESUMING you have already unplugged it and removed the cover, ground yourself by attaching a grounding strap to your wrist and the computer case to prevent static discharge
What is a Madison strap in electrical terms?
A Madison strap, in electrical terms, refers to a type of electrical connection or strap used in power distribution systems, particularly for grounding and bonding applications. It typically consists of a metal strap or bar that connects multiple grounding conductors or provides a link between grounding systems and equipment. The use of a Madison strap helps ensure the effective grounding of electrical installations, enhancing safety by reducing the risk of electrical faults.
What can be used to prevent electrostatic discharge?
grounding strap
Why should a person who handles electronic components wear a grounded wrist strap?
Correct Answer= "To reduce or eliminate static charges"
