Calculations in the field of direct current and direct current motors

Electrical formulae are often required for the voltage type "direct current". To simplify the handling,
we have expanded the "Online calculator" section with the formulae listed here.


P=U x I
P=I² x R
P=U² / R
P=W / t

Units of measurement used:

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