Direct Current and DC Motor Calculations

Electrical formulas for the voltage type "direct current" are often required. To simplify the process,  
we have expanded the "Online Calculator" section for you with the formulas listed below.


P = V x I
P = I² x R
P = V² / R
P = W / t


Measuring Units:

Power          P = Kilowatt  [kW]
Voltage        V = Volt  [V]
Current         I = Ampere  [A]
Resistance  R = Ohm  [Ω]
Work el.      W = Joule  [J]
Time             t = Seconds [s]
