KVA & Power Formulas
Power Formula-DC KVA | Power Formula-Single Phase KVA | Power Formula-3 Phase
Power(watts) = Voltage x
Current
W = E x I
Power(watts) = Voltage² /
Resistance
W = E² / R
Power(watts) = Current² x
Resistance
W = I² x R
KW(kilowatts) = W / 1000
mw(milliwatts) = W x 1000
VA = Voltage x Current
VA = E x I
Power(watts) = Voltage x Current x Power
Factor
W = E x I x PF
KVA = VA / 1000
KVA = E x I / 1000
Amps = KVA x 1000 / Volts
KW(kilowatts) = Voltage x Current x Power
Factor / 1000
KW = E x I x PF / 1000
VA = voltage x Current x 1.73
VA = E x I x 1.73
Power(watts) = Voltage x Current x 1.73 x
Power Factor
W = E x I x 1.73 x PF
KVA = VA/1000
KVA = E x I x 1.73 / 1000
Amps = KVA x 1000 / Volts x 1.73
KW(kilowatts) = Voltage x Current x 1.73 x
Power Factor / 1000
KW = E x I x 1.73 x PF / 1000
