There are following procedure to be adopted for correct dimensioning of a plant (i)             Load Analysis:- First step in dimensioning of a plant is to check for connected load and their location Now check for location of power distribution panels Now we can calculate cable requirement i.e. length of cables and path of cable laying Now we will do calculations of total power consumption while taking account utilization factors and demand factors (ii)           Transformer and generator size calculations:- Transformer and generator size are usually selected 15-30% more in comparison to total connected load considering future prospectus. (iii)          Conductor size selection - Now we calculate cable size according to load requirement of various connected loads. Cable selected may be copper or aluminum. Cables selection must also consider voltage drop at load current under specific reference conditions. (iv)          Selection of Protective circuit breaker:- Short circuit calculatio

Spark plug is used in all automobile engines whether it’s two wheeler, three wheeler, four wheeler or even bigger vehicles. Spark plug is an electrical device which is mounted on cylinder head of internal combustion engines, this electrical spark plug generated a spark which is used to ignites the compressed fuel uses in engines Spark plug consists of an insulated central electrode which in turn connected through an insulated wire to the ignition coil where ignition is required. This insulated wire may also be connected to the magneto circuit on the outside and form a grounded terminal on the base of the plug. A spark gap in cylinders of and Internal combustion engines is usually divided into:- (i)             Spark-ignition engines :- These engines required spark plugs to begin combustion, (ii)            Compression-ignition engines Known as diesel engines:-            In these engines air is compressed and then diesel fuel injection is done into the heated compressed air mixture w
