Hi @asi1993, thank you for participating in the Industrial Electrical Homework. We have assessed your Homework post , and the below captures our assessments.

---

A. Your ladder diagram drawing and definition is correct. You have drawn the ladder diagram by drawing an input and output symbol. (0.5 Mark)

B. You have drawn the ladder symbols of inputs and outputs and written their functions. I have shown some other ladder symbols in the lesson, which are very important. (1 Mark)

C. The ladder logic truth table of your AND and OR gates is incomplete. You have created a truth table without symbols and formulas, which is wrong. (1.5 Marks)

D. Your converted ladder diagram contains errors. Did not use NC here. (1 Mark)

E. You have drawn the series and parallel circuit of the battery and got the output correctly, but you have not shown it practically. Hope you understand your mistake. (1 Marks)

I commented asking you to refer to the source for drawing the ladder diagram but I didn't get your reply. I suggest you cite the source in any post on the Steemit platform.
