Worksheet for Series Circuits SAR Physics AM Kolchin Instructions 1. This worksheet is to be completed in class while work- ing together. Please don’t go ahead of the class. 2. Calculations are to be done showing equations and units. Please don’t just write down numbers without expla- nation. 3. No calculators are to be used unless explicitly stated. 4. The worksheet is to be handed in at the end of class even if it has not been completed. Series Circuits : 1. In a series circuit there is only one path for the current to take. 2. The resistances can be replaced by an ”equivalent resis- tance” that leaves the current unchanged. It is found by adding up all of the resistances in the series circuit: R EQ = R 1 + R 2 + R 3 + .... 3. Ohm’s Law ( V = IR or I = V/R ) can be applied between any two points in a circuit. 1

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
