Questions and Correct Answers Latest Update
Graded A+
Combustible Liquid
Ans: A liquid with a flash point ABOVE 100F
Current Flow
Ans: 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
