FORMULAS, EQUATIONS & LAWS


 
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)

 
DIRECT CURRENT
 
AMPS=WATTS÷VOLTS I = P ÷ E A = W ÷ V
WATTS=VOLTS x AMPS P = E x IW = V x A
VOLTS=WATTS ÷ AMPS E = P ÷ IV = W ÷ A
HORSEPOWER=(V x A x EFF)÷746
EFFICIENCY=(746 x HP)÷(V x A)
 
AC SINGLE PHASE ~ 1ø
 
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 PFW=V x A x PF
VOLTS=WATTS÷AMPS E=P÷IV=W÷A
VOLT-AMPS=VOLTS x AMPS VA=E x IVA=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)
 
AC THREE PHASE ~ 3ø
 
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)
