Here you can calculate the electrical power supplied, the current, and the resistance of e.g.,
DC motors.
P = I² x R
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]
