A liquid with a flash point ABOVE Combustible Liquid
100F
If the current flowing out from an 12.5
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?
If a hair dryer draws 8.3amps (in a 1000
home with 120-volt service), what is
the wattage?
*Power (P) = current (I) x voltage (V)
Watts = amps x volts
