    We require that you put some effort into assignments before we help.

    Understand that procrastenation on your part does not mean an emergency on our part.

    The first question is trivial, show us your work.

    Why in the world did you do the resistance in two steps? Isn't it obvious that all three resistances, 10 ohms, 5 ohms, and 4 ohms, are in parallel? And that, therefore, [tex]\frac{1}{R}= \frac{1}{10}+ \frac{1}{5}+ \frac{1}{4}[/tex]
