ET ATT COMP TEST || All Solutions are Accurate.
OSHA stands for: correct answers Occupational Safety and Health Administration
Minimum amount of current to "freeze" the body to a conductor: correct answers 12mA AC or
60mA DC
Different Current Amounts vs the Body: correct answers 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 answers Most serious type of burn, results from current flowing through
tissue/bone.
Arc Burns correct answers Caused by high temperatures near the body. Can be caused by arcs or
explosions.
Thermal Contact Burns correct answers Results from contact with high temperature surfaces.
The Law of Electrostatics States: correct answers Unlike charges attract and like charges repel.
Power Resistor correct answers Used with large current flows, are also known as "Wire Wound
Resistors."
Precision Resistors correct answers Have a tolerance of 1% or less. Used when exact resistance
values are necessary.
, Tolerance correct answers Measures the percent error of a resistor, the lower the tolerance the
more accurate a resistor's ohmic value.
Fuses correct answers Open when too much current melts them.
Signals on a Schematic flow from: correct answers Left to Right. Inputs on the left, outputs on
the right.
The power supply on a schematic is usually at: correct answers The bottom left.
All magnets possess: correct answers A North Pole
A South Pole
Flux Lines
Flux Lines correct answers Lines that form a magnetic field around the magnet, moving from
North to South outside the magnet.
Permeability correct answers How easy it is to magnetize something, the willingness of a
material to become magnetized.
Retentivity correct answers How well a material can stay magnetic, ability of a material to retain
magnetism.
Ferrous Particles correct answers Ferrous means iron. A material without ferrous particles is
NONMAGNETIC.
Left Hand Rule correct answers A method for finding the north pole of an electromagnet. The
thumb is the direction of the current, the fingers are the direction of the flux lines.
