Household electric wires are covered with plastic or other materials as insulation to prevent short circuits and fires, and to prevent electric shocks.
I believe you've managed to turn wires inside out. (conducting) wires are covered in insulating plastic. And it is done this way to prevent electrical energy from going where it is not wanted, such as into you.
There should be 2 or 3 wires. A hot, a neutral and sometimes a ground.
Yes as long as they are in a romex style wire. Like 12-2 for example. Which is individual wires incased in an outer jacket. You should never have just single wires running in the attic unprotected or anywhere for that matter. Individual wires must be in a conduit. And any splices should be in a box.
There should be no reason to install two ground wires in the same conduit. Code requires that only a single path should be required if it is to carry a fault current. This ground wire should be single and continuous from the device back to the distribution panel. It is the fault current that is carried on the ground wire that trips the breaker or fault protection device. Don't confuse grounding wires with bonding wires.

there is a 2 prong plug under the glove box, wires are covered by a green sheath. If there is a second one with 4 wires that's the ABS tester.
Yes, a cable is typically one or more wires or optical fibers bound together in a common protective jacket or sheath. The purpose of the jacket or sheath is to protect the wires or fibers from external elements and provide insulation.
Wires have to be insulated from each other to confine the current inside the wire. Most wires are insulated with a pvc sheath surrounding the copper wire.
You can not have a "neutral earth" the "neutral" and the "earth" are separate wires/connections and should not be cross connected or muddled up.

Exposed electrical wires should be immediately covered or insulated to prevent the risk of electric shock or fire. It is important to turn off the power source before attempting to handle or repair the wires, and it is recommended to seek the assistance of a qualified electrician to properly address the issue.
You have an oil leak
There are a variety of wire coverings depending on what the conductor is used for. There are also different wire coverings for different temperatures where the conductor will be used. To answer the question the wires in a circuit are covered in insulation.
Electric heat, heat rated insulation on wires, and instead of blk & whi colored wires under the pink sheath they are identified with a red & blk signaling that it's a 220v system.
Ground wires are typically bare wire or green covered. Common wires are white and hot wires are black. If you have black wires that are grounds or commons you should contact an electrician to ensure you don't have a problem on your hands. Sounds like someone who didn't know what they were doing has been mucking around in your panel.
AnswerBecause, it is a good insulator and won't conduct electricity. It is also flexible.It coated by rubber or plastic
