Why salt is needed to conduct electricity?
Ultrapure water is a bad conductor; you need a salt, which form ions, to increase the electrical conductivity.
What are the electrical properties of metal?
Metals are good conductors of electricity due to the presence of free electrons that can move freely within the metal lattice. They have low electrical resistance, high thermal conductivity, and can easily transfer electric charge. Metals also tend to have low electron affinity, allowing them to readily lose electrons and become positively charged ions.
Is plastic a good electrical conductor or insulator?
Plastic is typically considered to be a good electrical insulator because it does not conduct electricity well due to its high resistivity. However, there are certain types of plastic that have been engineered to be conductive for specific applications.
Is zinc a good or bad conductor?
About all we can do is compare zinc to some other metals. Zinc isn't a terrible conductor, but it isn't the greatest, either. Perhaps it might be best to classify it a fair as regards electrical conductivity. Here is a list of just a few metals and their electrical conductivity as "just a number" to make comparison easy: Aluminum 59Brass 28Copper (annealed) 100Gold 65Lead 7Mercury 1.66Platinum 15Silver 106Tin 13Titanium 5Tungsten 28.9Zinc 28.2 Zinc isn't great, but it isn't at the bottom of the list, either.
What does Good electrical insulator mean?
An insulator is a material that does not conduct well, so an electrical insulator is a material that does not conduct electricity well. A metal is a bad electrical insulator as it has delocalised electrons, therefore conducts electricity, but most plastics and materials like rubber do not conduct electricity, so they are good electrical insulators. Hope that makes sense and helps? :3AnswerAn insulator is a material with insufficient free charge carriers to support conduction.
What are the electrical properties?
good conductors of heat bad insulators low resistence high conductivity

Is any metal good conductor of heat but bad conductor of electricity?
Dear Asker,Is this a personal question? I believe it is. There is no metal that is a good conductor of heat but bad conductor of electricity. Why? Its because both conductive properties in metals comes from the reason that metals have free/mobile electrons. The more mobile electrons you have, the better conductor you are. Copper have a heat conductivity of 400 W/(m.K) while it have a electrical resistance of 1.68×10−8 ρ (Ω•m). It has high heat conductivity and low electrical resistance, just second to silver, which have a heat conductivity of 430 W/(m.K) while it have a electrical resistance of 1.59×10−8 ρ (Ω•m).sincerelyJet

What are the differences of metal and non metal?
Metals are good conductors of heat and electricity, are ductile, malleable and shiny, and most of them are solid (except mercury). A non metal is a bad conductor of heat and electricity, are not malleable, ductile or shiny, and can be a solid, liquid, or gas.

Metals are good conductors of electricity due to the presence of free electrons that can move freely within the metal lattice. They have low electrical resistance, high thermal conductivity, and can easily transfer electric charge.

What insulates better aluminum or plastic?
Aluminum is a better insulator than plastic because it has a lower thermal conductivity. This means that aluminum is better at preventing the transfer of heat than plastic. However, plastic can be better at blocking sound and electrical conductivity.
How are metalliods different from metals?
Metalloids have some properties similar to properties of non metals; metalloids have bad thermal and electrical conductivity, they are brittle, soft etc.
Are bad conductors of electricity used to cover electrical wires?
No, materials with a high insulation value factor are used to cover electrical wire to provide a barrier from the wire shorting out to ground. By using the term "bad conductors" states that there is conductivity to a degree.
Why is Styrofoam a good insulator?
Styrofoam is a very porous material; air from the closed pores has a bad thermal conductivity.
Is styrofoam a good insulation?
Styrofoam is a very porous material; air from the closed pores has a bad thermal conductivity.
Are metals a bad conductor of electricity?
No. Metals are good electrical conductors.
