No, polythene is a plastic and that cannot conduct electricity.
Yes, in other words it's a poor conductor of electricity, they use it to coat wires so that the electricity flows to the right places.
Not a good one.
Ways to reduce electrical resistance: increase the diameter of the conductor, decrease or increase the temperature of conductor (depending on its thermal characteristics), decrease the length of the conductor. A change in the material out of which the conductor is made can decrease resistance, too. And there is the phenomenon of superconductivity. In a simple circuit the resistance can be lowered by adding resistors in parallel. The total circuit resistance will then decrease. You can also reduce resistance by substituting resistors of lower value, or by adjusting a potentiometer, or pot, to a lower value.
A vacuum is a non conductor.
Aluminium is a metal and metals are good conductors of electricity. Metals also tend to conduct heat,sound and energy.
Conductor
Conductor combining the functions of both a protective earthing conductor and a neutral conductor
yes
Wood is a thermal insulator. It is a poor conductor of heat.
The thermal conductivity of a perfect conductor is 1
Something that conducts thermal energy well is a thermal...conductor. If it does not conduct well it is called an insulator.
Aluminum is a conductor of thermal energy and electrical energy.
Graphene is the best thermal conductor. Any metal or metallic objects such as a frying pan would be a good thermal conductor, including diamond.
Yes, that is what "good thermal conductor" means.
No
Yes, it is a material with a high thermal conductivity.
steel
i forget
A material that is a good thermal conductor would hold in a lot of heat. These thermal conductors would also transfer heat easily.
