Which item is listed as an example of Electric Electronics of Working Elements?

• A. Electric Motors, Solenoids, and Linear Motors
• B. Cylinders
• C. Directional Valves
• D. Switches

Answer: (A)

Electric motors, solenoids, and linear motors are devices that take electrical energy and convert it into mechanical motion, which is exactly what “Electric Electronics of Working Elements” refers to. Motors provide rotational motion from electricity; solenoids use magnetic attraction or repulsion to create linear motion; linear motors generate linear motion directly through electromagnetic force. The other options don’t fit because cylinders are fluid-powered actuators, directional valves are control devices that route fluid rather than produce work, and switches are electrical controls that don’t convert energy into motion.
