Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus. It is a major global health problem. It can cause chronic infection and puts people at high risk of death from cirrhosis and liver cancer. A vaccine against hepatitis B has been available since 1982. The vaccine is 95% effective in preventing infection and the development of chronic disease and liver cancer due to hepatitis B.
Kilovolt-amp (kVA) kVA is kilo-volt-ampere. kVA is a unit of apparent power, which is electrical power unit. 1 kilo-volt-ampere is equal to 1000 volt-ampere: 1kVA = 1000VA. 1 kilo-volt-ampere is equal to 1000 times 1 volt times 1 ampere: 1kVA = 1000â1Vâ1A. kVA to volt-amps calculation.
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.
