Looks like you have a Wheatstone bridge. Why don't you try Wikipedia.\n\nhttp://en.wikipedia.org/wiki/Wheatstone_bridge

That is known as the "solid height" of a spring; when all the wires are stacked on top of eachother.  You can calculate it by just multiplying the number of turns of the spring by the diameter of the wire.

I think they mean an inductor that's not tied to ground.

Braided fishing line would work...get as heavy as you can.

it is called a gyro, it goes right under the neck if the handlebars. it is really a sealed bearing that turns when pulled. think of a baring with posts on the out side and the inside if u grab all of the posts then u can spin the baring all the way around will just put break cables on the post and their u go. a Gyro.

The Stren “J” Knot - Perfect for Braid-to-Mono Connection\n\nStren, manufacturer of the most dependable fishing lines in the world, introduces its “J” Knot, the perfect connection when joining a monofilament or fluorocarbon leader to a braided mainline. It also excels when connecting monofilament to monofilament, or monofilament to fluorocarbon.\n\nThe “J” Knot is the creation of David Justice, the R & D Manager for Stren Lines. .\n\nThe “J” Knot is similar in its initial stage to the Surgeon’s Knot, but thereafter goes to an alternating weave on each side of the overhand knot. It is superior to the Surgeon’s Knot because the cutting pressure is taken off the mainline by alternating sides.\n\nSimple directions on how to tie the Stren “J” Knot: For a diagram see: http://www.lyndenhuggins.com/Fishing/Knots/J%20knot.jpg\n\n1. Lay the line and leader alongside each other, overlapping about 12 inches.\n\n2. Treating the two like a single line, tie an overhand knot, pulling the entire leader through the loop.\n\n3. Leave the loop of the overhand knot open, pull the tag ends of both line and leader through the bottom of the overhanging loop, and then through the top again. (For a mono leader to a braid connection, pull the tag ends    through the bottom once again.)\n\n4. Holding both lines and both ends, begin to draw the knot slowly and evenly. If the knot appears to have loose sections after the initial draw down, be sure to pull the loose ends tightly into the knot. Make sure the knot is tight and compact by pulling all ends snugly.\n\n5. Trim ends closely.

When you're working with current traveling through a wire, you may run across the need to do this kind of approximation.

because they are not grounded, in fact, u can sometimes see utility workers high up on the tension wires with thousands of volts going right over them

its the cables that use to carry the electricity. see any book on power system, such as stevenson

Well it dosn't seem like that big of a deal. So just let it go till the next time you take the RV in for service or inspection have them take a look at it. It may just be a loose  wire since the switch still retracts it.

Usually they are there to improve the visibility of the wire and grab your attention.  You don't want a tall sailboat going under low wires do you?

It is called static electric.

Yes very good insulation as most domestic wiring is insulated with PVC there are some specialist plastics which can be made to conduct electricity but not normaly.\njust to add for all the people saying that it is not an insulator my work involves working on live overhead line equipment up to 11000 volts and the only thing that keeps me alive is the plastic insulation on the truck and tools
