Answer: B
Share your understanding of this question with the correct explanation.
The power flow of a DC motor, with respect to a DC generator, is reversed.
A DC generator converts mechanical energy into electrical energy, while a DC motor converts electrical energy into mechanical energy. In other words, a generator produces electrical power as its output, while a motor consumes electrical power to generate mechanical power.
Since the direction of energy flow is reversed between a generator and a motor, the power flow is also reversed. When a DC generator is supplying power to a DC motor, the power flows from the generator to the motor. However, if the motor is acting as a generator (due to the mechanical load driving the motor), the power flow is reversed, and power flows from the motor back to the generator.
Therefore, the correct answer is B: reversed.
