ET ATT COMP Test Questions With Correct
Answers 100% Verified
OSHA stands for: - CORRECT ANSWER -Occupational Safety and Health Administration
Minimum amount of current to "freeze" the body to a conductor: - CORRECT ANSWER -12mA
AC or 60mA DC
Different Current Amounts vs the Body: - CORRECT 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 - CORRECT ANSWER -Most serious type of burn, results from current flowing
through tissue/bone.
Arc Burns - CORRECT ANSWER -Caused by high temperatures near the body. Can be caused by
arcs or explosions.
Thermal Contact Burns - CORRECT ANSWER -Results from contact with high temperature
surfaces.
The Law of Electrostatics States: - CORRECT ANSWER -Unlike charges attract and like charges
repel.
, Power Resistor - CORRECT ANSWER -Used with large current flows, are also known as "Wire
Wound Resistors."
Precision Resistors - CORRECT ANSWER -Have a tolerance of 1% or less. Used when exact
resistance values are necessary.
Tolerance - CORRECT ANSWER -Measures the percent error of a resistor, the lower the tolerance
the more accurate a resistor's ohmic value.
Fuses - CORRECT ANSWER -Open when too much current melts them.
Signals on a Schematic flow from: - CORRECT ANSWER -Left to Right. Inputs on the left, outputs
on the right.
The power supply on a schematic is usually at: - CORRECT ANSWER -The bottom left.
All magnets possess: - CORRECT ANSWER -A North Pole
A South Pole
Flux Lines
Flux Lines - CORRECT ANSWER -Lines that form a magnetic field around the magnet, moving
from North to South outside the magnet.
Permeability - CORRECT ANSWER -How easy it is to magnetize something, the willingness of a
material to become magnetized.
Retentivity - CORRECT ANSWER -How well a material can stay magnetic, ability of a material to
retain magnetism.
