Metals are conductive, but are not perfect conductors and so they have some electrical resistance. How the resistance of the metal is affected by "thickness" depends on what you mean by thickness. If the electrical current has to flow through a longer piece of metal, then the resistance of the metal to electrical flow would be greater. However, if you take that same length of metal and increase the area of the metal by increasing its "thickness", then the resistance of the metal becomes less.

Does heating a metal wire increase or decrease its electrical resistance?
it so increases it
Which metal has no resistance?
99.99% silver is the best for no resistance.
What are electrical conduit fittings used for?
An electrical conduit is a tube used to protect and route electrical wiring in a building or nonbuilding structure. Electrical conduit may be made of metal, plastic, fiber, or fired clay. Most conduit is rigid, but flexible conduit is used for some purposes.
What is the difference and similarities between paper clip and electrical wire?
they are the same metal
What raw materials were used when making the playstation 3?
electrical parts,metal, plastic, rubber circuuit boards, seb terry solamite and electrical wire casing
Characteristics of copper?
Corrosion resistance and electrical conductivity. and its metal
What is an Grade an answer to what affects the resistance in a wire?
*the resistivity of the metal the wire is made of *thickness of wire *length of wire
Does electrey faster in thick wire or thin one?
The speed of an electric signal or current depends on the material, not on the thickness. In metal, it is usually about 2/3 the speed of light in a vacuum. On the other hand, a thin wire has a higher electrical resistance than a thick wire (other things being equal). But this does not affect the speed.
If the temperature of a metal conductor increases the electrical resistance of the conductor usually?
increases
Does heating a metal wire increase or decrease its electrical resistance?
it so increases it
What is the principle of electric iron?
Heat generated by electrical resistance. Thermal mass of a metal plate.
Cookware what is meaning of anodized?
From Wikipedea; Anodizing "Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called "anodizing" because the part to be treated forms the anode electrode of an electrical circuit. Anodizing increases corrosion resistance and wear resistance, and provides better adhesion for paint primers and glues than bare metal".
What is the working principle of electric iron?
Heat generated by electrical resistance. Thermal mass of a metal plate.
What would reduce resistance in a copper wire?
Reduce the resistance:-- Use a shorter piece of wire.-- Use thicker wire.-- Cool the wire.Increase the resistance:-- Use a longer piece of wire.-- Use thinner wire.-- File a nick in the piece of wire you have.-- Stretch the wire.-- Heat the wire.
What is the thickness of metal brake pipe in a car?
Most metal pipes thickness are 25 mm
What happens to the resistance of metals as they get hot?
The electrical resistance in a common piece of metal such as copper wire would increase. This happens because as temperature increases the atoms of the metal vibrate quicker and to a larger extent resulting in a greater number of collisions for electrons moving along the metal.
How much time does it take in electroplating?
Michael Faraday worked out that the thickness of metal electroplating deposits in a certain time depends on the amount of electrical current, the concentration of the solution and the position the metal holds in the 'electrochemical series.'
