Ohms Law Calculator

Enter any two known values and press 'Calculate' to solve the remaining values. For example, for a freshly charged battery at 4.2 volts and an atomiser with a resistance of 1.2 ohms, enter 4.2 in the Volts box and 1.2 in the Ohms box, then press 'Calculate' to find the Amps and Power. (You should get a result of 3.5 Amps and 14.7 Watts) Remember to press the Reset before each new calculation.



Voltage (E) = Current (I) * Resistance (R)
Power (watts) = Current Squared (I^2) * Resistance (R)
Power = I*E = E^2 / R
