ATT ET COMP TEST 2024 WITH QUESTIONS AND ANSWERS. OSHA stands for: - ANSWER Occupational Safety and Health Administration 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.
