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.
kVA is the âapparent powerâ, while kW is the actual, or real power in a alternating circuit. kW is the amount of power capable of doing work, while kVA is the âvectorial summationâ of KVAR and KW. kW is kilowatts, while kVA is kilo Volts Amperes. kVA is equal to kW in DC circuits because the voltage and current are in phase.
