Hi @hamidrizwan, thank you for participating in the Industrial Electrical Homework. We have assessed your Homework post , and the below captures our assessments.

---

A. You have explained us very well by drawing the ladder diagram. A ladder diagram has two or one input and one output. (0.5 Mark)

B. You have drawn the two input and output symbols of the ladder diagram and written its function correctly. But there are other ladder symbols such as counters. Learn about other ladder symbols. (1 Mark)

C. You have drawn the ladder circuit according to the three-input truth table which is correct. I am very happy with your drawing. But it would have been a better presentation if you had done it practically. I have cut some numbers due to not showing practicals. (3.5 Marks)

D. Ladder wiring is correct from your electrical wiring. I am satisfied with your answer. You will practice with more ladder diagrams later. (1.5 Mark)

E. Your series and parallel circuit diagram with battery is correct. But you didn't show practically so some marks are deducted. (1. 8 Marks)

After reading your homework, I understand that you have learned a lot about ladder diagrams. Continue this learning curve and you will be successful. Good luck to you.
