Ohms law 


Give me any TWO numeric values and I'll give you all FOUR. Press the Ohm's Law button after you have made your entries:

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 = VOLTAMPERES
kVA = KILOVOLTAMPERES
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 
VOLTAMPS= 
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 
VOLTAMPS= 
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)
