Overview

5. Course Topics Electricity Phenomena ~ 3.5 - 4.0 weeks
Charge and Charge Distribution
Electric Field – interaction of a charge/charge distribution with its “environment”
Electric Force – interaction between (among) charges/charged objects
Electric Potential – interaction of a charge/charge distribution with its “environment”, an alternate approach
First a qualitative approach, then a quantitative approach
Lab Activities
TEST #1

6. Course Topics II DC Circuits ~ 1.5 - 2.0weeks
Basic Circuits – the process of “powering” electronic and electrical devices
Simple Circuits – series, parallel, and combination circuits
Non-Simple Circuits – looking at more “sophisticated” circuits
RC Circuits – using capacitors to store energy or power a circuit
Lots of lab activities
TEST #2

7. Course Topics III Magnetic Phenomena ~ 2.0 weeks
Magnetic Field – interaction of moving charged particles/current-carrying wires with their “environment”
Magnetic Force – interaction between (among) moving particles, current-carrying wires
Electromagnetic Induction – the interaction between electric and magnetic phenomena
First a qualitative approach, then a quantitative approach
Lab activities
TEST #3

8. Course Topics IV AC Circuits and Waves ~ 1.0 – 2.5 weeks
AC Circuits – a process of generating alternating outputs for a variety of uses
Electromagnetic Waves – interacting electric and magnetic fields propagating through space or a medium
Light (Optics) – an example of EM Waves
Lab Activities
TEST #4 (Optional)

9. On Overview – Maxwell’s Equations
Gauss’ Law of Electric Fields
Gauss’ Law of Magnetic Fields
Faraday’s Law of Induction
Ampere’s/Maxwell’s Law

10. On Overview – Maxwell’s Equations
Gauss’ Law of Electric Fields
Gauss’ Law of Magnetic Fields
Faraday’s Law of Induction
Ampere’s/Maxwell’s Law

11. Lorentz Force
Force of interaction between charges and moving charges (or currents) and a magnetic field

12. Electricity and Magnetism Conceptual Survey
Conceptual survey of your ideas on electrostatic and magnetism
Does involve “formal” language (i.e. physics language)
NOT FOR A GRADE
It is a survey of your current understanding of electrostatic and magnetism ideas

14. Electric Charges and Their Properties
Read pages 3-15.
How many different types of electric charges occur in nature?
Where does charge come from in nature?
What is the fundamental “carriers of charge” in nature?
What is the charge of these fundamental carriers?
Example P-1
Charged is quantized!
Net charge of a closed system does not change!
How can “objects/things” not be electrically charged?

15. Charge Production Experiment

16. Electric Charges and Their Properties II
What is the polarization of atoms?
Figures 5
What is an induced dipole?
Conductors and Insulators
Figure P-6
Polarization of Insulators
Figure P-7 & P-9
Polarization of Conductors
Figures P-10 & P-11 (What’s Wrong)
Charging, Polarizing and Discharging

17. Perfect Conductors and Perfect Insulators
Electric charges are free to move without any restrictions to their motion.
Example - metals
Perfect Insulators
Electric charges can not move, regardless of the amount of force applied to them.
There are no static electric fields present inside perfect insulators.
Example – plastic, rubber
