Concentric castles were the next follow on from stone keep castles. Concentric castles, in Britain, are most associated with Edward I and North-West Wales where a series of huge castles were built. The most famous concentric castles are at Harlech, Beaumaris, Caernarvon and Conway.
Unlike square keep castles, concentric castles had no central keep. In many senses, they had no centre either as all parts of the castle would have been considered to be a strong point. Each concentric castle had a very heavily defended entrance and the central core was defended by a series of curtain walls. The furthest of the curtain walls would have been the smallest in height to allow the defenders to see an approaching enemy. The curtain wall nearest to the castle would have been the highest to give the defenders the maximum height advantage over those attempting to take over the castle.

Yes, the higher the conductivity concentration the higher the conductivity value in the material. Some times the conductive particles are surrounded with insulating materials which cut the conductive paths between the electrodes and as a result it stops the increase in the conductivity values to a certain limit according to the structure (texture) in the material.
The highest degree of electrical conductivity is in silver.
Metals have a higher electrical and thermal conductivity than nonmetals.
Both thermal conductivity and electrical conductivity tend to be higher in metals than in most other materials.
yes
it means the rate transfer of heat through this metal and coductivity is the measure of this abillity
The electrical conductivity of the solution will be higher if the concentration of NaCl increase.
conductivity is a result of free electrons meaning that they can be riped away fast and the temperature of the material. a colder material has a lower resistance and higher conductivity. materials like metallic oxides have low conductivity and materials like pure copper and aluminum have high conductivity.
kcl...more reactive
the ability to conduct heat.
Thermal and electrical conductivity are physical properties; they represent the ability of materials to conduct heat or electrical current.
5.8e7 is a larger number than 9.5e5. 5.8e7 can be written as 58,000,000, and 9.5e5 can be written as 950,000. Conductivity is a measure of the ability of a material to conduct electricity. A large conductivity means that the material conducts electricity well. The units of electrical conductivity are siemens per meter (Sm-1).
