Free application to calculate kVA, HP, KW, Amps and Volts in a electrical circuit.You just have to set the values and click on the Calcul button, the result will be then displayed.You can select the type of circuit: single phase and three phase.Features: - calculate kVA from amps and voltage - calculate volt from kVA and amps - calculate amps from volt and kVA - convert kVA to hp and kW: the conversion will be instantly displayed when kVA value is setA kilo-volt-ampere (kVA) is the unit used for the apparent power in an electrical circuit. The apparent power equals the product of root-mean-square voltage and current.In direct current circuits, this product is equal to the real power in watts.A perfect application if you are a student or electrical engineering.
