Symbolic: E =VOLTS ~or~ (V = VOLTS)
P =WATTS ~or~ (W = WATTS)
R = OHMS ~or~ (R = RESISTANCE)
I =AMPERES ~or~ (A = AMPERES)
HP = HORSEPOWER
PF = POWER FACTOR
kW = KILOWATTS
kWh = KILOWATT HOUR
VA = VOLT-AMPERES
kVA = KILOVOLT-AMPERES
C = CAPACITANCE
EFF = EFFICIENCY (expressed as a decimal)

AMPS= | WATTS÷VOLTS |
I = P ÷ E | A = W ÷ V |
WATTS= | VOLTS x AMPS |
P = E x I | W = V x A |
VOLTS= | WATTS ÷ AMPS |
E = P ÷ I | V = W ÷ A |
HORSEPOWER= | (V x A x EFF)÷746 |
EFFICIENCY= | (746 x HP)÷(V x A) |
AMPS= | WATTS÷(VOLTS x PF) |
I=P÷(E x PF) | A=W÷(V x PF) |
WATTS= | VOLTS x AMPS x PF |
P=E x I x PF | W=V x A x PF |
VOLTS= | WATTS÷AMPS |
E=P÷I | V=W÷A |
VOLT-AMPS= | VOLTS x AMPS |
VA=E x I | VA=V x A |
HORSEPOWER= | (V x A x EFF x PF)÷746 |
POWERFACTOR= | INPUT WATTS÷(V x A) |
EFFICIENCY= | (746 x HP)÷(V x A x PF) |
AMPS= | WATTS÷(1.732 x VOLTS x PF) |
I = P÷(1.732 x E x PF) |
WATTS= | 1.732 x VOLTS x AMPS x PF |
P = 1.732 x E x I x PF |
VOLTS= | WATTS÷AMPS |
E=P÷I |
VOLT-AMPS= | 1.732 x VOLTS x AMPS |
VA=1.732 x E x I |
HORSEPOWER= | (1.732 x V x A x EFF x PF)÷746 |
POWERFACTOR= | INPUT WATTS÷(1.732 x V x A) |
EFFICIENCY= | (746 x HP)÷(1.732 x V x A x PF) |
