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.
Both are power units. Voltage multiplied by current. The difference is normally KVA has a power factor following it i.e., it is used in Ac measurements. KW = Kilo volt * Current. KVA = Kilovolt * Current * power factor. When power factor =1, then KVA = KW. The AC loads have characteristic called Power factor depending on the load whether it is inductive or capacitive. The power factor will be either lagging or leading which are opposite in polarity to each other in simple form.
