Combustible Liquid - ANSWER A liquid with a flash point ABOVE 100F
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

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)
