What are the three main functions of grounding?

• Personnel safety

• Equipment protection

• Electrical noise reduction

• Wifi connection

What are the three subsystems of the facility ground system?

• Earth Electrode

• Fault protection

• Signal reference

• Electrostatic

• Radio Frequencies

What facility ground subsystem is also known as the "safety ground?"

• Fault protection subsystem

• Voltage reference subsystem

• Toaster-bathtub lock

• Signal reference

The Signal reference subsystem is often called the "signal" ground as it establishes the _______ for signal circuits and controls electrical noise and static in a facility.

• rf carrier frequency

• water line

• voltage reference

• breathing space

_______ is the conductive path between the earth and grounded object.

________ is the establishment of a low-impedance path between two metal surfaces and is essential in all communications and power ciruits.

Bonds can be made in a many ways such as welding, brazing, soldering, or by compression using bolts, nuts, and special straps which make up two different types of bonding. what are they?

• direct bonding and inderect bonding

• thermal bonding and friction bonding
• magnetic bonding and electrical bonding
• chemical bonding and covalent bonding

Corrosion introduces impedance, or opposition to the total current flow, into the bond which is why you do not want to bond _______ metals which are susceptible to corrosion.

• flammable
• conductive
• unlike

• insulated

Electrostatic Discharge (ESD) is the ​ (a)   flow of electricity between two electrically charged objects and is caused by the ​ (b)   of an electric charge on one surface that is suddenly transferred to another surface when they ​ (c)   .

• sudden
• buildup
• touch
• slow
• smelly

__________ us another name for static electricity or electricity at rest.

• Kinetic electricity
• Moving electricity
• Triboelectricity

• Dynamic electricity
