The Voltage Divider

Choose resistances (two different pairs) that will allow you to answer the following questions. If $R_2$ is twice as big as $R_1$, what voltages will appear across each? Calculate the answer and see if you are right. If $R_2$ is 1/10 the value of $R_1$, what then? Again, perform the calculation and see if you are correct. Compare theory and experiment. For definiteness, set your power supply on stun, I mean, 10.
