copper iron losses

(i) Copper loss is the energy lost due to heating of copper coils of transformers. (ii) Iron loss due formation of induced current in the iron line resulting in lot of heat. (iii) Leakage of magnetic flux. All flux linked with primary may..

. Aluminium does not oxidise (corrode) as quickly as its reactivity would suggest. Once a thin oxide layer of (Al 2 O 3 ) has formed on the surface, it forms a barrier to oxygen and water and so prevents further corrosion of the aluminium. Aluminium is a useful structural metal. It can be made hard..

. The heaviest metal lead also tarnishes in moist weather. The black coating on silver and the green coating on copper are examples of corrosion in which the oxides formed strongly bond to the surface of the metal, preventing the surface from further exposure to oxygen and consequently sl..

It is caused due to the deficiency of iron. Iron is necessary for the production of haemoglobin, a protein that is an oxygen carrier in blood. When the level of haemoglobin drops in the blood it results in the person feeling tired easily, loss of appetite, loss..

A D.C. motor consists of a rectangular coil made of insulated copper wire wound on a soft iron core. This coil wound on the soft iron core forms the armature. The coil is mounted on an axle and is placed between the cylindrical concave poles of a magne..

Reduces the nitrite ions to ammonium ions. Nitrite reductase does not require molybdenum and may contain copper and iron. Since ferredoxin is the direct source of electrons, this reaction takes place in the leaves and the nitrite ions formed elsewhere are also transported to lea..

Electroplating is a process of depositing a thin layer of a fine and superior metal (like chromium, zinc, nickel, gold etc.) over the article of a baser and cheaper metal (like iron, copper, brass), with the help of electric curre..

Solids with a definite geometric pattern. Examples: Iron, copper, silver, sulphur etc. are some elements which form crystalline solids. Potassium chloride, sodium nitrate etc are some of the compounds, which are crystalli..

Metals such as iron, zinc, lead, copper, etc., are in the middle of the reactivity series. These are moderately reactive metals and are usually present as sulphides or carbonate..
