Question

Assertion (A): Electric actuators are used control system for high torque applications.

Reason (R): Due to linear speed-Torque characteristics.

(a) Both A and R are true and R is correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A is false but R is true

This question was addressed to me in an online interview.

This intriguing question originated from Controller Components topic in section Control System and Components of Control Systems

Answer 1

The correct option is (a) Both A and R are true and R is correct explanation of A

Explanation: Electric actuators are the devices that are used to convert non measurable form of energy into measurable and are used in high torque applications due to linear speed torque characteristics but not used in low speed where hydraulic actuators are still used.
