Hey all,

Just a quick question, I'm trying to combine these resistors together but I'm not getting the right answer. I'm pretty close though. This picture should explain my steps:

Thanks!

 

Looks OK so far.

 

One more simplification (R4 is parallel to everything on the left side) and you've reached the final goal.
Good job so far. ;-)

 

Yeah I thought it looked correct as well but the answer I get differs from the right one >.<. Can you guys help me out?

It's Question 9: http://www.allaboutcircuits.com/worksheets/dc_sp.html

I keep getting something around 1.1kΩ for the total resistance. What am I doing wrong?

 

Whoops, never mind. I just had a calculator problem! I got it right, thanks guys!
