Calculator variables & definitions
Below are the definitions for the different terms that this calculator uses
What is Voltage?
Electric potential, measured in volts (V), indicates how much electrical potential energy exists per unit of charge at a specific point in a circuit. This difference in potential—called voltage—is what drives electric charges to move through the circuit.
What is kVA?
kVA, or kilovolt-ampere, is a unit of apparent power in an AC (alternating current) electrical system. It represents the combination of both real power (used to perform work) and reactive power (used to sustain electric and magnetic fields).
What are Amps?
Amps, short for amperes, measure the electric current in a circuit—that is, the rate at which electric charge flows through a conductor.
What is a transformer?
A transformer is an electrical device that changes voltage levels from one value to another. It can either step voltage up (increase) or step it down (decrease), depending on the application.
