Is there any materials, besides rubber, that electricity can't travel through?

Question

I mean, like, the guys changing the wires and stuff wear really thick rubber glove-type-things. I was wondering if there was any different materials they could use.

Answer 1

Actually water doesn't conduct electricity either, its the minerals in it. You can take two pieces of wire( one for pos one for neg) hook a male plug to one end, so you can plug it up. And a light socket to the other. Cut one of the wires into(doesn't matter which) stick each end down into a glass of water, across from each other. Put some water into the glass so the wires are submerged(use clean water, tap works for me) plug it up. If the water has no minerals in it the light won't come on, add a little salt or dirt, whatever. And the light will come on. Wouldn't put my finger in it though. Shows you water doesn't conduct electricity.

Gold is the best conductor, that's why satellites are so expensive. Silver, Copper, Aluminum are others.

Semiconductors is whats used to make electrical eye's on stoves, heating elements in heaters. Tungsten is in light bulbs. Steel, Iron, Tungsten are semiconductors. Semiconductors resist/conduct electricity which in turn give off heat and light.

Resistors are things like rubber, glass, plastic, paper and wood as long as their isn't any water in them

Answer 2

Yes all materials have a resistance to electrical current. It varies quite a lot for metals too, Copper and silver are very good conductors.

Creamics have very high resistance to electrical current. Just look up at the things on the poerlines between the wire and were it joins the pole.

Answer 3

Electricity can travel through/along rubber, just not very easily. If electricity has another option, it will take most of those options over rubber. Other substances, like glass, are also good electrical insulators.

Answer 4

I believe current may travel through or along rubber materials if given enough juice.

Answer 5

Ceramics, plastics, gasses, glasses--these are all good electrical insulators. Anything which is not metallic (in the sense of opaque and shiny) is a good insulator. Nothing is a perfect insulator--it depends on the voltage difference and across the insulator and the thickness of the insulation.

Answer 6

Plastic

Answer 7

And wood

Answer 8

wood?
