1.	Which among the following represents an illustration of closed loop system?(a) Automatic washing machine(b) Automatic electric iron(c) Bread toaster(d) Electric hair drierI have been asked this question during a job interview.My enquiry is from The Design Problem in portion Design of Control Systems
Answer» CORRECT choice is (a) Automatic washing machine Explanation: CLOSED loop control system is the system with the positive or negative feedback and this is made so as to avoid the DISADVANTAGES of OPEN loop control system and in the above options automatic washing machine represents closed loop system.
