Lab Activity

Part 1

Click here to run the circuit simulation. Answer the questions below in your lab notebooks.

 

  1. Create a series circuit to light one single bulb and sketch your circuit.
  2. Create a circuit made up of more than one bulb and a single battery. Build your circuit so that if there is a gap in your circuit all of the bulbs go out. Sketch and identify your circuit type.
  3. Create a circuit made up of more than one bulb and a single battery. Build your circuit so that if there is a gap in your circuit only one bulb goes out. Sketch and identify your circuit type.

 

Part 2

1. Build a series circuit with two light bulbs.

2. Open grab bag and add one of each item into your circuit. Draw a table in your lab notebook. Record your observations and identify each object as an insulator or a conductor in this table.

PostLab

Answer the following questions in your lab notebooks using complete sentences.

  1. If you were designing a lighting system for your room, which conductor would you use for the wiring and which circuit would you set up? Explain your logic and provide examples from the lab. 
  2. Think of an average house/apartment: In which part of the dwelling would it be appropriate/useful to set up a series circuit? In which part of the dwelling would it be appropriate/useful to set up a parallel circuit? Explain your reasoning for each.
