Unit Objectives:

Electrostatics

By the end of this unit, you will be able to:

-       Calculate force, electric field strength, and electric potential, as well as draw electric field lines, for a variety of charge distributions

-       Differentiate between conductors and insulators, induction and polarization

Electrodynamics

By the end of this unit, you will be able to:

-       Solve for equivalent resistance, voltage, current, and power in simple and complex circuits

-       Explain how electrical equipment works, such as a resistor, battery, power supply, diode, and capacitor

-       Draw and understand circuit diagrams with many components

-       Analyze patterns of charging and discharging capacitors

Lab Skills

By the end of this unit, you will be able to:

-       Power light bulbs and LED’s in series and parallel

-       Set up a circuit on a breadboard; identify circuit components and read the color coding on a resistor

-       Measure voltage, resistance, and current using a multimeter

-       Measure an electric signal using an oscilloscope

Over the course of this unit, you will:

-       Build an AC to DC converter (part of a phone charger)

-       Analyze your own electrical energy usage and discover ways to reduce it

-       (Time permitting) Build an audio filter

Prerequisite skills: Understanding of position, velocity, and acceleration; mathematical reasoning; adding vectors; solving problems using Newton’s Laws and energy conservation; basic waves vocabulary; physics lab experience
