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.
K stands for kilo or 1,000. VA stands for (Volts X Amps) Kilo (Volt X Amps) or just (kVA) is the apparent rate, expressed in quantities of 1,000 VoltAmps, at which energy is being transferred. Kilo Watts (kW) is the real rate, expressed in quantities of 1,000 Watts, at which energy is being transferred. kW = kVA X (power factor).
