On an overhead service, during periods of rain, water will run along the overhead service wires. Water would run in to the service riser and in to the top of the meter, the drip loop allows the water to drip off of the conductors instead of running in to the meter.
So that water will not get in the mask
Rainwater will run down the outside of the service cable, and drip off the bottom of the loop. Without the loop, rainwater could more easily enter into the building along the cable.
You form a drip loop so water sheds off of the wire and doesn't run down somewhere it shouldn't such as a panel or meter socket.
To stop rain water from entering the service stack.
Drip loops prevent water from following the electrical service conductor into the service panel, causing shorts and other dangerous situations. So long as the low point in the cable is below the main lugs, water will collect and drip from there, and not continue to the exposed live parts of the panel. We usually have a drip loop in a place right next to the place the conductor penetrates into the head or the place where it "goes through" a wall or barrier. That way there is only a short "uphill" run between the drip loop and the penetration point for the conductor.
It allows for water to cascade off the lowest point of the wiring BEFORE it enters the head of the service pipe...for the same reason wiring CANNOT be routed below fluid lines in aircraft. 5 years FAA Airframe & Powerplant mechanic
to prevent loose ends
use a mild acid such as phosphorus fertilizer, some are specielly adapted for just that purpose

This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma.

One can purchase a robin loop tester from Ebay. One can also purchase a robin loop tester from electrical shops or from electrical dealers which carry robin loop testers.
There is no such thing as an "electrical citric".
The purpose of a drip tray is to protect water leaking to the floor service level. This is to prevent any water damage to the floor and or other floor areas.

The purpose of a drip leg in the gas piping is used as a device to capture dirt and debris from entering the furnace.
