ET ATT COMP TEST questions with verified answers A+ Grade
2026\2027
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.
