Series components always split up the voltage of the power supply. Resistance based components split up the voltage based on their percentage of the total resistance. Many circuits depend on using fixed value resistors to set a fraction of the supply voltage to part(s) of the circuit.
Whatever you attach to the output will become part of the voltage divider. So you almost always want it to be very high resistance, and usually some kind of amplifier. Topics covered later.

Percentage of resistance towards positive versus negative determines the output voltage.
