Name two environmental conditions common to the places where computers are most commonly used that encourage the build up of static electricity.
What two inexpensive and easily used tools should the technician have in order to ensure that computer components will not be damaged by ESD?
As long the wall outlet is wired properly and the system is ________________ in and
_______________ off then the case will provide ground.
As soon as the computer case cover has been removed the technician should put on the
__________________________ and clip it to any bare metal surface of the system's
______________________
The industry manufacturers estimate that at least _____________________ dollars worth of returned computer components have been returned because they have been damaged by ESD.
The anti-static wrist strap contains a ________________ resistor to prevent a bad
electric shock in the case of a _______________ circuit or faulty outlet wiring.
The best defense against being shocked by a system plugged into an outlet that is wired
wrong is to use an ___________________ on the outlet first.
The total number of free electrons that have gathered in a body represent the total
_______________ that will act on them when given the chance.
The larger the difference between free electrons in two bodies that come into contact,
the larger the _______________ of them that will move into the deficient body when they make contact.
The average minimum potential in an electrostatic discharge that is required in order to
be felt by a human is roughly ___________________ volts.
The BIOS EEPROM chip is reprogrammed with _______ volts, an amount much smaller than what can be felt by a human during an electrostatic discharge.
The CMOS RAM chip built into the motherboard runs on ___________________ an extremely small amount of power that can easily be delivered from a human fingertip in an ESD.
Describe the two types of ESD damage that improperly grounded technician’s can do to computer circuitry.
Insulators have excellent ________________ properties one of the aspects of these
properties is that they easily accumulate ________________ electrons.
List two common materials found in the normal computer environment with high dielectric properties.
List and describe four physical properties of metals that are the direct result of the way the outer electron shells of the metal crystal allow electrons to wander between atoms forming a loose electron "soup":
______________ is the measure of a force acting on a body that causes it to be displaced or moved.
______________ is the rate at which work is performed. This is why batteries or the wall
outlet are referred to as _______________ sources.
