ATT Comp Test QUESTIONS AND CORRWCT
ANSWERS WITH VERIFIED SOLUTIONS.
OSHA stands for: - ANSWER: Occupational Safety and Health
Administration
Minimum amount of current to "freeze" the body to a conductor: -
ANSWER: 12mA AC or 60mA DC
Different Current Amounts vs the Body: - ANSWER: 1-5 mA: Faint tingling
to slight shock
6-16 mA: Painful shock, shaky muscles
17-99 mA: Extreme pain, hard to let go, heart flutters begin
100-2000 mA: Heart flutters definite, severe muscle contractions, nerve
damage, significant chance of death.
2000+ mA: Cardiac arrest, organ damage, severe burns, certain death.
Electrical Burns - ANSWER: Most serious type of burn, results from current
flowing through tissue/bone.
Arc Burns - ANSWER: Caused by high temperatures near the body. Can
be caused by arcs or explosions.
Thermal Contact Burns - ANSWER: Results from contact with high
temperature surfaces.
The Law of Electrostatics States: - ANSWER: Unlike charges attract and
like charges repel.
, Power Resistor - ANSWER: Used with large current flows, are also known
as "Wire Wound Resistors."
Precision Resistors - ANSWER: Have a tolerance of 1% or less. Used
when exact resistance values are necessary.
Tolerance - ANSWER: Measures the percent error of a resistor, the lower
the tolerance the more accurate a resistor's ohmic value.
Fuses - ANSWER: Open when too much current melts them.
Signals on a Schematic flow from: - ANSWER: Left to Right. Inputs on the
left, outputs on the right.
The power supply on a schematic is usually at: - ANSWER: The bottom
left.
All magnets possess: - ANSWER: A North Pole
A South Pole
Flux Lines
Flux Lines - ANSWER: Lines that form a magnetic field around the magnet,
moving from North to South outside the magnet.
Permeability - ANSWER: How easy it is to magnetize something, the
willingness of a material to become magnetized.
