Hi @jozzie90, thank you for participating in the Industrial Electrical Homework. We have assessed your Homework post , and the below captures our assessments.

---

A. Nice presentation as you have drawn the ladder diagram and given the definition. But you should remember that NO is normally open which is switch closed ie 0. On the other hand NC is switch on i.e. 1. Hope you understand. (0.5 Mark)

B. You just drew the ladder symbols of the input and output devices and wrote the function. But there are some other important ladder symbols that I have covered in the lesson. Learn more about ladder symbols. (0.9 Mark)

C. You have created AND and OR gate truth tables but not written symbols and formulas. Truth tables and practicals are impossible without the symbols and formulas of our AND and OR gates. Hope you understand your mistake. (2 Marks)

D. Converting your electrical wiring diagram to ladder diagram is correct. But if you practice ladder diagram more then you will be successful. (1.5 Mark)

E. You have tested the voltage and current by arranging the batteries in series and parallel. Your circuit design is correct. However, practical work remains incomplete. But I understand you understand battery series and parallel. (2 Marks)

I have reviewed your homework and pointed out the mistakes. You will learn the input and output symbols better for learning the ladder diagram. Good luck to you.
