QUESTIONS AND SOLUTIONS
GRADED A+
◉ 12.5.
Answer: If the current flowing out from an electrical panel is 12.5 amps,
and it then flows through an electrical load of 1500 watts, what is the
amperage of the remaining current flow of the return circuit?
◉ 1000.
Answer: If a hair dryer draws 8.3amps (in a home with 120-volt
service), what is the wattage? *Power (P) = current (I) x voltage (V)
Watts = amps x volts

Answer: What temperature in the upper gas layer causes the onset of
Flashover?
,◉ 1960°F.
Answer: The temperature at which copper melts
◉ 2 W/cm2.
Answer: The measurement of the radiant heat flux (from gas layer to the
floor) that indicates the onset of flashover
◉ 240 volts.
Answer: The voltage between the two hot wires at the service entrance
cables in most single-family residences in the United States (single-
phase service with three wires)
◉ 3 years.
Answer: The revision cycle for NFPA 921 (timespan)
◉ 350°F.
Answer: The flash point of power steering fluid
◉ 35-70 p.s.i..
Answer: In high-pressure fuel-injected vehicles, this is the typical range
of pressure that is used to pump fuel from a fuel tank
◉ 5 and 17.
, Answer: The lower explosive and upper explosive limit of natural gas
(methane)?
◉ 680°F.
Answer: The ignition temperature of power steering fluid
◉ Fuel.
Answer: Any substance that can undergo combustion
◉ Act or Omission.
Answer: Two factors or situations leading to a fire that may show the
nature of the incident responsibility.
◉ Additional Investigative Recommendations.
Answer: This concept should not be included in a summary report of
findings.
◉ Admiralty Law.
Answer: A law that may govern the fire investigation of a boat
◉ After-market Equipment.
Answer: A type of device in a vehicle, which can cause an electrical
overload to factory installed wiring
