5 bad conductors of electricity

Answer 1

-- the starter and the cigarette lighter in a car
-- the filament in a light bulb
-- the third rail on the commuter-train track
-- the heater wire in the toaster
-- the AC line cord from the refrigerator
-- the 'voice coil' in a loudspeaker
-- the coax cable down from the TV antenna or satellite dish
-- the ethernet cable from your modem to your laptop
-- the waveguide up to the microwave dish
-- the plasma column inside a strobe tube or neon sign

Answer 2

silver, copper, gold, aluminum, calcium, beryllium, tungsten

These are some of the best conductors. There are many more at different levels of conductivity. Other factors such as temperature affects a materials level of conductivity. Water varies in conductivity depending on purity. Pure distilled water is actually an insulator, tap water is somewhat conductive and salt water is considerably conductive.
