14. What do DC and AC stand for?
15. True or False: An electron holds  a positive charge
Expert Solution
Step 1

(13)

GFCI detects the differential current between hot and neutral wire conductor if differential current between these two wires is greater than 0.002 Ampere then it trips.

GFCI trips at differential current of 0.002 Ampere or more.

Step 2

(14)

DC stands for direct current whose amplitude is always constant respect to time.
