====== compare the difference between three LEDs in series and parallel ======

Build the following circuits on the circuit board with a 6V battery pack and compare. Be very careful to build the circuits as specified, paying close attention to which components should be parallel or in series.

  - three LEDs and one 150 ohm resistor in series
  - one 470 ohm resistor and three parallel LEDs 
  - two 470 ohm resistors and three LEDs in series
  - two parallel 470 ohm resistors feeding into three LEDs in series
  - one 150 ohm resistor for two parallel LEDs, each with its own switch

Take photos of each of your circuits.

Answer the following questions about the circuits.

  - In the series circuits (resistors in series or LEDs in series), what happens when you remove one of the series components?
  - In the parallel circuits, what happens when you remove one of the components?
      - What about the resistors?
      - What about the LEDs?
  - What behavior do you notice in the circuit with two switches?

Put your photos and answers to the questions on an assignment page on the wiki.
