| To find the desired voltage on the used electric motor, it is necessary to use Ohm’s law: I = U / R, from where we express: U = R * I.

Values of variables: R – resistance of the used electric motor (R = 250 Ohm); I – current strength (I = 0.4 A).

Calculation: U = R * I = 250 * 0.4 = 100 V.

Answer: The voltage on the used electric motor is 100 V.
