  3. This is a link to a metacafe video of a gas station static electricity accident.

Electricity (and magnetism) units:--Submitted by David Derbes.

Equipotential Surfaces & Field Lines - Modified from Joe Stieve - You can purchase (or get for free) from your local grocery store the plastic trays in which they sell vegetables and cakes. Print the graph paper and glue it to the underside of the tray. This lab works great everytime. I've modified it for time constraints for just point charges, but you can attach metal stripping to represent a line of charges.

LB Capacitance AP: Build and Test a Capacitor:
  1. Written by Paul Beeken. This file includes a succinct section of notes & directions for creating and testing a capacitor charge holding capability and the discharge rate of the capacitor.

E Field Mapping Problem Solving lab from the U of MN
  • here is the pdf version and the word version
  • a common tweak is to plot a 3-d graph of the data in Excel to get a unique feel of th E fields.
E&M Electrostatic Notes: Here are Wayne Mullins E&M Statics notes.

PowerPoint from Peggy Bertrand

Electricity Concept Map from Chris Becke
  • This concept map, most useful for B, shows the relations between the F E U and V equations for both point charges and uniform fields. When my students can recreate this from scratch, the relationships and equations are set in their brains!

CIRCUITS


Circuit Notes: Here are Wayne Mullins Circuit Notes. They are great. Wayne saves me time and again. Posted by plulai w/ permision from W. Mullins.

Graphics for making circuit images
  • If you are in need of a reasonably simple way to create circuit diagrams for tests, quizzes, labs, the schematic elements within this PowerPoint will allow to quickly and easily create them so you can copy/paste into other applications.
  • Only minimal PowerPoint skills required

Home Circuit Lab
  1. Author: Paul Lulai plulai@stanthony.k12.mn.us
  2. Lab Type: Problem Solving
  3. Students design a mock-up circuit of a house. They must write-up a schematic diagram, use resistors to adjust voltages & currents (motors & bulbs will operate within their designated ranges), create parallel & series circuits. After schematic approval, students make & test the circuits.
  4. We use 14-2 grounded wire, switches, outlets, & screw caps from Menards / Home Depot / Lowes. We use small 3V motors from a surplus supply store (We use Official AxeMan parts).
  5. The bulbs & Outlets operate at 1.5 V while the motor operates at 3V. This follows most real homes. Most outlets at 120V & outlets for Fridges, dryers etc.. at 240V. Granted these Voltage ranges are accomplished in different manners, but I believe it makes a point with students.
  6. Part 2 has students create a power source to operate the house circuit. The house circuit in part one is powered with 2 D cell batteries.

Circuit Problem solving lab from the U of MN
  • Here is a link to the pdf version and the word version.
  • I usually start with Colorado's PhET sims on Lab Prob 1, then move to real DMM's for the lab probs 2 - 5 that we do.

Batteries, Bulbs, Graphs (and Ohm's Law):
  • author: plulai@stanthony.k12.mn.us
  • A simulation lab using PhET.
  • Students create a circuit with n-bulbs (each lab table uses a different number of bulbs).
  • Lab develops Ohm's law in a kinda Modeling manner.

An R-C circuits lab

  • By Jeff Cagle jrcagle@juno.com
  • Students use a transistor-driven LED to measure capacitance by the time constant.


RC, RL, and LC Labs
  • By Peggy Bertrand pbertrand@ortn.edu
  • This PowerPoint was presented at the Physics C forum in Orlando, Florida, in February 2012. It describes labs for these three types of circuits.


Household Energy Audit
  • By John Bernecker
  • A project where students estimate their household energy use and investigate various sources for electrical power.

AP Physics 1 Electricity Problem Set - Problem set built by Bob Enck, Dan Fullerton and Paul Sedita in an effort to start an AP-1 style problem bank. Feel free to print/use in your classrooms. Please don't re-post the files themselves, but rather only the links to the files, to allow us to quickly and easy update and continue to build upon these problems. Thank you! -- Dan Fullerton (dfullerton@aplusphysics.com). PS - anyone interested in adding on to these problems, we'd love the help!
