ET ATT COMP TEST QUESTIONS WITH
ANSWERS
Question 1
OSHA stands for:
Correct Answer
Occupational Safety and Health Administration
Question 2
Minimum amount of current to "freeze" the body to a conductor:
Correct Answer
12mA AC or 60mA DC
Question 3
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.
Question 4
Electrical Burns
Correct Answer
Most serious type of burn, results from current flowing through tissue/bone.

Question 5
Arc Burns
Correct Answer
Caused by high temperatures near the body. Can be caused by arcs or explosions.
Question 6
Thermal Contact Burns
Correct Answer
Results from contact with high temperature surfaces.
Question 7
The Law of Electrostatics States:
Correct Answer
Unlike charges attract and like charges repel.
Question 8
Power Resistor
Correct Answer
Used with large current flows, are also known as "Wire Wound Resistors."
Question 9
Precision Resistors
Correct Answer
Have a tolerance of 1% or less. Used when exact resistance values are necessary.
Question 10
Tolerance
Correct Answer
Measures the percent error of a resistor, the lower the tolerance the more accurate
a resistor's ohmic value.

Question 11
Fuses
Correct Answer
Open when too much current melts them.
Question 12
Signals on a Schematic flow from:
Correct Answer
Left to Right. Inputs on the left, outputs on the right.
Question 13
The power supply on a schematic is usually at:
Correct Answer
The bottom left.
Question 14
All magnets possess:
Correct Answer
A North Pole
A South Pole
Flux Lines
Question 15
Flux Lines
Correct Answer
Lines that form a magnetic field around the magnet, moving from North to South
outside the magnet.
