Circuits Lab 1

Lab1 terminology Quizlet

This simulator is pulled from University of Colerado PHET interactive simulators:

Part A Materials:

  • You are using the PHET simulator above for all of Part A

*** You must complete and show Mr.Nannan Part A before proceeding***

Part B & C Materials

  • ONE cell
  • Wire leads
  • light bulb (1-10)

Part D Materials:

  • You are using the PHET simulator above for all of Part D

Series Connection:


1. Usually does not need as much wire (cheaper to make).

2. Series circuits do not overheat easily. This makes them very useful in the case of something that might be around a potentially flammable source, like a Christmas tree!

3. Series circuits are easy to learn and to make. Which means that it’s simple to conduct repairs .

4. More power devices can be added, together they can create a large potential difference.

5. The current that flows in a series circuit has to flow through every component in the circuit. Therefore, all of the components in a series connection carry the same current.


1.If one point breaks in the series circuit, the total circuit will break.

2. As the number of components in a circuit increases, the resistance will increase for the whole circuit.

3. Changes to the circuit can not be made safely without shutting off the power to the whole circuit.

Parallel Connection:


1. Every load that is connected in a parallel circuit gets the exact same amount of voltage.

2. It is very easy connect or disconnect a new element without affecting the working of other elements.

3. If any fault happened to the circuit, then the current can continue to move through one of the different paths in the circuit.


1. Needs WAAAAY more wires (so could cost more to run the same number of loads).

2. Voltage can NOT be increased using a parallel connection.

3. It is difficult to make every part of a parallel circuit have the same current.
