March 14, Nodal Analysis

The purpose of this lab is to develop a circuit to testify if our calculation using nodal analysis is correct. We have 3 resistors represent cable which are 100ohm, and 2 220ohm in series, and 2 1k ohm resistors in parallel. Then we have a 12V battery source from left, and a 9V battery source from right. Then we use our nodal analysis to calculate what current values are going through each battery and power rating of the battery. Then we run the circuit and measure the current and voltage through the battery source. We find:
                              I(1)=17.4mA             I(2)=1.33mA
                              P(1)=210.54mW       P(2)=11.97mW
The value is really close to what we calculated.
