R1 V. + R2 12 R3 https://drive.google.com/file/d/1WJUWDo8q7wGCQmwBgMvR04B_SY-MNJNN/view?usp=sharing Consider the circuit in Figure 2. We will assume that both the power supply's potentials V and V, along with the resistors R, through R3 are known quantities where the currents flowing through the circuit are unknown. Since there are three unknown currents in this circuit, three linearly independent equations are needed in order to determine them. Again, type out all equations below as if you were writing the equations into Python. Write an equation for the currents entering in/out of the top junction in Figure 1. Use I| as the current coming from the left, 12 as the current going downward, and I3 as the current going to the right.
