Hi, I have to do the drawings in the drawing in Proteus, but I do not succeed, I do not understand something. You can help me.Thanks.

Wow... A bit of a mess.... I doubt anyone can help on this information.. You are going to have to do the drawings in paint then explain some of your symbols... I don't recognise them..

Moved to homework help!!

It should measure current and voltage in DC (voltage and current divider)

From what I remember it was a transistor, but he said we could use buttons more easily

Er! I think you have tried to copy the circuit from memory!
Is this what's required?

Yes it is, except that they are combined and I had 1/8, which does not appear in the drawing.
And there's the one above that would be something of a power divider, which I don't know how to do

no power divider,sorry.Current divider

Try again, voltage divider.

yes those that I did give them that is, but it is the one above in the first drawing, I was referring to it

Then the current in the "voltage divider" will differ from circuit to circuit... Hence so will the voltage... To get 5V from 20 and keep the same ratio's you'll need a regulator or at least a Zener!

Well it's impossible to tell anything from the first drawing, it's looks mostly like a spider has just crawled through a blob of ink

What a hurtful comment, spiders deserve our respect.

the first drawing signifies a part of a DC multimeter that measures current and voltage

from 5v to 20v is the measuring range
