Electrical Engineering XYZ MCQs
Which of the following is an example of the actuator:
- Hydraulic motor
- Electric motor
- Pneumatic motor
- All of these
Correct answer: 4. All of these
Explanation: An actuator is a device that converts energy into mechanical movement or action. All three options listed (hydraulic motor, electric motor, and pneumatic motor) are examples of actuators, as they each convert different forms of energy into mechanical motion.
- Hydraulic Motor: It converts hydraulic (fluid) energy into rotational mechanical motion. Hydraulic motors are commonly used in various applications, such as industrial machinery and vehicles.
- Electric Motor: It converts electrical energy into rotational mechanical motion. Electric motors are widely used in numerous applications, ranging from household appliances to industrial machinery.
- Pneumatic Motor: It converts pneumatic (compressed air or gas) energy into mechanical motion. Pneumatic motors are often employed in situations where the use of electricity or hydraulics may not be practical, such as in certain industrial and automotive applications.
So, all of the options (hydraulic motor, electric motor, and pneumatic motor) are examples of actuators because they perform the essential function of converting different types of energy into mechanical movement.
