hello I have three questions for logic circuits. If you can help me pleas.

 

This sounds like it should be in the homework section.
Sorry, we don't do homework here, but we will help you with yours if you show what work you have done to try to solve the problem.

 

First one. I choose 1.6
Second . I choose 250
Third . 471

So pleas if you know the answer. Tell me. I need to know. Thank you so much

Only your second answer is right.
How did you calculate the other two values?

Can you tell me how can I calculate them ?

You still don't get the program. You show us what you did and how you got your result. Then, and only then, do we show you where you went wrong. You'll remember things for the exam much better if we do it this way. You can continue to insist on your way, but if you do, then we can't help you because we don't know what you don't understand about the problem. Only by seeing where you went wrong can we provide the information that you need. Do you get the idea?

All you need is basic arithmetic and Ohm's law.
I assume you are familiar with both?
