Here you can calculate the electrical power supplied, the current, and the resistance of e.g.,
DC motors. 

P = I² x R
Power: P
Current: I
Resistance: R
Please fill all mandatory inputs.

For Example:

A direct-current motor (or DC motor) has a rated current of 25 amperes and the resistance of 4.8 ohms.
What electrical power results from these specifications? 

 

P = I² x R
P = (25 A)² x 4.8 Ω
P = 3 kW

 

Measuring Units:  

Power           P = Kilowatt  [kW]
Electricity      I = Ampere [A]
Resistance   R = Ohm [Ω]
