Good conductors of electricity are often good conductors of heat?
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
Are insulators dull brittle and poor conductors?
Insulators are conductors
What type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
What are some good conductors and bad ones?
Good Electrical conductors: All metals, ionic substances (in solution or molten form) Bad Electrical conductors: Water Good Heat conductors: All Metals Bad Heat Conductors: Water
What are good conductors called?
They're called conductors. As opposed to insulators, which don't conduct. Metals are typically pretty good conductors.
Who were Metropolitan opera conductors in 1965?
This would include - House conductors as well as guest, rehearsal and stand-ins. The only way to obtain a full listing would be to apply to the Met's librarian.

Is it true that shield wires conductors located above the phase conductors protect the phase conductors against lightning?
Yes, but they're not 'phase' conductors, they're 'line' conductors.
Ceramic material used in bricks?
thy are good because they are not heat conductors so they don't transfer the heat as fast as heat conductors does, if they would you wouldn't be able to stand on a tile where the sun shine is rising on it because it would get really hot, and in a quick time.
If ther are more than conductors in the raceway the ampacity of the conductors must be derated?
Ampacity must be derated depending on the number of conductors and the ambient temperature. In the Canadian Electrical Code Table 5C denotes derating for the number of conductors. 1-3 conductors = 100% load 4-6 conductors = 80% 7-24 conductors = 70% 25-42 conductors = 60% 43 or more conductors = 50%
