Here you have the possibility to calculate the electrical power supplied, the voltage,
and the resistance of e.g., DC motors.

P = U² / R
Power: P
Voltage: V
Resistance: R
Please fill all mandatory inputs.

For Example:

A 24 volt direct current motor (or DC motor) has a resistance of 4.8 ohms.
What electrical power results from these specifications? 

P = V² / R
P = (24 V)² / 4.8 Ω
P = 0.12 kW or 120W

 

Measuring Units:

Power          P = Kilowatt [kW]
Voltage        V = Volt [V]
Resistance  R = Ohm [Ω]
