 OHM’S Law Calculator

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:

 VOLTS AMPS OHMS WATTS

 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 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)

 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 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)

 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)  Picture gallery | Knowledge Base | Contact us | Site map |
