Lesson 2 Static Electricity

When working in an area filled with flammable liquid and vapors, you must wear shoes with

• Steel toe protectors

• Leather soles

• Rubber heals

• Steel heel plates

Bonding minimizes the potential difference between

• Two objects

• An object and the earth

• Static and current electricity

• Protons and neutrons

A grounding wire should be

• Solid

• Flexible

• AWG No. 8 or smaller

• At least AWG No. 8

Electrically charged atoms are called

• Neotrons

• Protons

• Ions

• Eons

To guard against spark ignition in a tank, you should

• Bond it

• Ground it

• Purge it

• Ground and Purge it

The kind and amount of charge generated when removing dust does NOT depend on the

• Properties of the surface material

• Size of the particals

• Amount of contact

• Humidity

If you use conductive dressing on a belt, you must apply it

• Sparingly

• Thickly

• Frequently

• Infrequently

To prevent damages to a bearing by static discharges, you can bond the shaft to the bearing by means of a

• Grounding wire

• Conductive dressing

• Metal or carbon brush

• Metal comb

When using static electricity in spray painting, what kind of charge is given to the object being painted?

• Positive

• Negative

• Either positive or negative

• Neither positive nor negative

The most sensitive instrument for measuring static electricity is the

• Electrostatic amplifier

• Electrostatic volt meter

• Electroscope

• Staticscope
