For the circuit below, which is my attempt at drawing a face with circuit elements, find the current passing through resistors 1, 2, and 3. For each say if the current is going up or down as it passes through the resistor. $V_1 = 8.00 \text{ V}$, $V_2 = 9.00 \text{ V}$, $V_3 = 5.00 \text{ V}$, $R_1 = 3.00 \Omega$, $R_2 = 9.00 \Omega$, and $R_3 = 2.00 \Omega$. Assume $I_1$ is over $R_1$, $I_2$ is over $R_2$, and $I_3$ is over $R_3$. $I_1=$ Direction = $\text{O up O down}$ $I_2=$ Direction = $\text{O up O down}$ $I_3=$ Direction = $\text{O up O down}$
