Series and Parallel Circuits Physical Science Name: ____________________________________________________ Period: ___ Date:____________ Essential Question: How do I explain direct current electrical circuits? Instructions: Study pp. 450-452 and answer the following questions series circuit In a electricity has only one path to follow. All parts are connected one after another. Electrons flow from the negative side of the battery around in a loop to the positive side. Draw arrows to show the path of the electricity in this series circuit. If a light bulb is missing or broken in a series circuit, will the other bulb light? Explain. _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ parallel circuit In a , electricity has more than one path to follow. Electrons can follow different paths as they flow from the negative side of the battery to the positive side. Draw arrows to show the different paths electrons can travel in this parallel circuit. If a light bulb is missing or broken in a parallel circuit, will the other bulb light? Explain. _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ Super Teacher Worksheets - www.superteacherworksheets.com.

Think!________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ 10. What is electrical resistance? _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ 11. What is ohm or ohms ( Ω ) _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ 12. What is volts ( V) _____________________________________________________________ _____________________________________________________________ ______________________________________________________ because the path the electricity needs to follow is broken. Yes because the electricity can travel along a different path and avoid the broken bulb.
