Electrostatic amplifier
Minimizes the potential difference between two objects
Bonding
A metal bar having many points
A static comb
How large must bonding and grounding wires be?
Large enough to carry the largest currents likely to occur
When filling a tank, when should you make electrical connection between the pipe and fill the tank?
Before opening the dome
To prevent damage from static discharge in a bearing, you can bind a shaft to the journal housing by means of a
Brush made of metal or carbon
To guard against spark ignition in a tank you should
Ground it and purge it
The kind and amount of charge generated when removing dust does NOT depend on the
Humidity
When using static electricity in spray painting, what kind of charge is given to the object being painted?
