Resistors in series or one after?
Creating a 3.3 V voltage potential output from a 5 V voltage source using 10K resistors could be done using the following diagram of a simple voltage divider, using the following equation.

\$ V_{out} = V_{1} \cdot \frac{R_2 + R_3}{R_1 + R_2 + R_3} = 5 V \cdot \frac{20 k \Omega}{30 k \Omega} = 3.33 V \$
