COMPLETE SOLUTIONS
◉ 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.
◉ Retentivity
Answer: How well a material can stay magnetic, ability of a material
to retain magnetism.
