Ohm's LawHome
Enter any two values. While entering your 2nd value the remaining values will be calculated and filled in automatically.
I=Current=Amps
P=Power=Watts
R=Resistance=Ohms
V=Voltage=Volts
Formula Reference:
I=V ÷ R=P ÷ V=P ÷ R
P=V x I=V2 ÷ R=I2 x R
R=V ÷ I=P ÷ I2=V2 ÷ P
V=I x R=P ÷ I=P x R
