The lactic acid bacteria convert the sugar in milk (lactose) to lactic acid. The rennet contains enzymes that modify proteins in milk. Specifically, rennet contains rennin, an enzyme that converts a common protein in milk called caseinogen into casein, which does not dissolve in water.
KVA is a unit of power. From ohms law it can be shown that in any circuit, the power of any element in the circuit is the product of the voltage and current (V x I) . Hence KVA is 1 Kilovolt times an Ampere and hence 1000 volts times an ampere. A unit of apparent power, equal to 1,000 volt-amperes; the mathematical product of the volts and amperes in an electrical circuit. A term used to describe the product of currend and voltage, expressed in kilovolt ampereres (KVA). KVA is the unit of transformer rating.
kW is the unit of real power & kVA is the unit of Apparent power. Apparent Power= real power + reactive power. Besides this,the ratings which we write on a motor or generator is KVA & not KW. B'coz there are two types of losses in a motor or generator- core losses & ohmic losses.
