I created a few photo shop images to help organize the problems I am having.

First, I have a basic circuit with a 12v battery and 5 resistors. For each resistor I need to find the currents through and voltages across. Below is the circuit diagram and table.

I was able to calculate R equivalent by adding R3, R4, and R5 in parallel to obtain 1ohms. I then added R1 and R2 with the 1ohms to obtain a equivalent resistance of 12ohms. With the information I now know that the current out of the battery is 1amp. The voltage across R1 is 2v considering V = iR = (1A)(2ohms) = 2v. Therefore, the voltage drop is 2v. Where i get stuck is determining the voltage and current for the other resistors. When i go to calculate the current through R3 I know (v/R) = i. I plug in the numbers, (10v/2ohms) = 5A!?! No way, If anything it is .5A because the current splits. Can anyone help direct me through completion of this problem? I assume I am on the correct path.

Also, if anyone has any additional time could you help me determine the breadboard layouts for these circuits?

Thanks in advance to anyone who provides any suggestions or help, I greatly appreciate it.
