Series and Parallel Circuits Virtual Lab

I recommend you select "intro" mode, although you can use either "intro" mode or "lab" mode.

Steps and Questions
  1. Connect a single light bulb to a battery, so that the light bulb lights. For this lab, use two two wires with alligators clips and a light bulb.
  2. Now, connect two light bulbs in a row. This is called a series circuit.
  3. Try unscrewing one of the light bulbs from the series circuit. What happens to the other light bulb?
  4. Now, connect the two different bulbs on two different branches. This is called a parallel circuit.
  5. Try unscrewing one of the light bulbs from the parallel circuit. What happens to the other light bulb?
  6. In which circuit were the light bulbs brighter, series or parallel?
  7. To wire the lights in your house, which type of circuit would you prefer, series or parallel? Explain two reasons why.
