Understanding Electrostatic Discharge (ESD)

The video, presented by Brandon from Lenovo, covers electrostatic discharge (ESD), its effects on computer components, and prevention methods. ESD is the sudden flow of static electricity between objects with different charges, which can damage electronic components. The video explains immediate and latent damage types and introduces an ESD field kit with tools like an anti-static mat, alligator clip, and wrist strap. It also provides tips for preventing ESD, such as grounding techniques, proper clothing, and workspace setup. The video concludes with a summary of ESD's impact and prevention strategies.

What is electrostatic discharge (ESD)?

• A sudden flow of static charge between two objects.

• A gradual build-up of static electricity.

• A type of electrical current used in computers.

• A method to increase computer speed.

Which of the following is an example of experiencing ESD?

• Using a remote control.

• Charging a mobile phone.

• Turning on a light switch.

• Feeling a shock after touching a doorknob.

What is immediate damage caused by ESD?

• Damage that causes a component to stop working instantly.

• Damage that can be easily repaired.

• Damage that is not visible.

• Damage that occurs over time.

What is latent damage caused by ESD?

• Damage that is immediately visible.

• Damage that is easily detectable.

• Damage that enhances component performance.

• Damage that degrades a component over time.

What is the purpose of an anti-static mat in an ESD field kit?

• To provide a comfortable workspace.

• To ground yourself and the machine you are working on.

• To store computer components.

• To increase static charge.

How does an ESD wrist strap function?

• By increasing static charge on the user.

• By insulating the user from static electricity.

• By grounding the user to the ESD mat or alligator clip.

• By providing a decorative accessory.

What should you do to minimize ESD risk when working inside a computer?

• Keep all cables connected.

• Stand on a hard surface.

• Wear wool clothing.

• Sit on a carpeted floor.

Why is it important to remove jewelry before working on a computer?

• To prevent damage to the jewelry.

• To avoid scratching the computer.

• To reduce the risk of ESD.

• To improve concentration.

What type of clothing should be avoided to reduce ESD risk?

• Silk clothing.

• Wool or synthetic clothing.

• Denim clothing.

• Cotton clothing.

What is the main takeaway from the video on ESD?

• ESD only affects large electronic devices.

• ESD prevention is unnecessary.

• ESD can cause both immediate and latent damage to electronics.

• ESD is not a concern for electronics.
