Hey Guys... Having a hard time telling the difference between Parallel and Circuits in series... I know it should be pretty easy. Here is the circuit im dealing with..
Each Resistor is 15 ohms.
Can you guys tell me the Total resistance?
Maybe that will help me figure it out... Thanks

k thats exactly what I got... I came up with a total resistance of 70.72.... The next question asked is what is the current in all the resistors. I suppose this is the part that messed me up. When I use V-total=(I-total)(R-total) I get...
8/70.72 = .113A
The current will only change when there is a junction so the current through r1,r2,r3 and r4 is .113A.
When there is a junction I used the values for Y and R7 and said the voltage drop was the same for both.
After R1, R2, R3, and R4 this leaves me with 1.2Volts. The voltage drop has to be the same so each one (Y and R7) will drop .6Volts. When I use V = IR for Y and R7 I end up getting .04 for R7 and .013 for Y... And that does not add up to .113
Am I missing something?... Thanks for your help btw
