The current in the electric motor is 0.4 A, and its resistance is 250 Ohm. What is the tension at its ends?

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.
