Q: What does OSHA stand for?
Answer✔✔ Occupational Safety and Health Administration
Q: What is the minimum amount of current that can "freeze" the body to a conductor?
Answer✔✔ 12mA AC or 60mA DC
Q: How does the body react to different amounts of current?
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
Q: What is the most serious type of electrical burn?
Answer ✔✔ Electrical burns, caused by current flowing through tissue/bone
Q: What causes arc burns?
Answer ✔✔ High temperatures near the body due to arcs or explosions
Q: What causes thermal contact burns?
Answer ✔✔ Contact with high temperature surfaces
, Q: What does the Law of Electrostatics state?
Answer ✔✔ Unlike charges attract and like charges repel
Q: What are power resistors used for?
Answer ✔✔ Large current flows; also called "Wire Wound Resistors"
Q: What defines precision resistors?
Answer ✔✔ Tolerance of 1% or less; used when exact resistance is necessary
Q: What is tolerance in resistors?
Answer ✔✔ Percent error; lower tolerance means higher accuracy
Q: How do fuses work?
Answer ✔✔ They open when too much current melts them
Q: In which direction do signals flow on a schematic?
Answer ✔✔ Left to Right; inputs on the left, outputs on the right
Q: Where is the power supply typically shown on a schematic?
Answer ✔✔ Bottom left
Q: What do all magnets possess?
Answer ✔✔ A North Pole, a South Pole, and Flux Lines
Q: What are flux lines?
Answer ✔✔ Lines that form a magnetic field from North to South outside the magnet
