Batteries can power DC motors.

• A. True
• B. False
• C. Not specified
• D. Only for some

Answer: (A)

Batteries provide direct current, which is exactly what a DC motor needs to operate. A battery stores chemical energy and delivers electrical energy as DC voltage. A DC motor converts that electrical energy into rotational mechanical energy through the interaction of magnetic fields in its windings with magnets. In practice, you can control the motor’s speed by adjusting the voltage or using techniques like PWM, and the battery’s ability to supply sufficient current affects torque and speed. Most brushed and brushless DC motors are designed to run directly from a DC power source, so a battery is a common and suitable power option. Some motors can also run on other supplies (like AC) when designed for that, but the basic fact remains: batteries can power DC motors.
