Topic 11.1 Lesson 1: Electromagnetic Induction

Emf, Magnetic Flux, Faraday's and Lenz's Laws.

In Topic 11, we will start really digging into the mysteries of the universe, primarily including with a very bizarre phenomenon upon which nearly all of our technology relies heavily: electromagnetic induction.

We will run through the slides and then you should take a run at this handout:

• Handout 1 (blank)

• Handout 1 (solutions)

After completion of the handout, please move onto test yourself questions in Tsokos and make sure you have completed the reading. The electromagnetic lab simulation is a fun way to increase your understanding, as well. 

Topic 11.2 

Transmission of Power

In Topic 11.2, we'll examine how generated electricity in transferred from power plants to homes and businesses, and how alternating current is converted to direct current via a process called rectification.

My dislike of this inferior PowerPoint presentation should not prevent you from accessing it.

Topic 11.3 

Capacitors.

Do you enjoy electronic devices? Music? Synthesizers? Phones? Computers? Good, you should. They are all loaded with capacitors and in Topic 11.3 we will learn how they work and behave. I hope you also like exponential decay.

Some additional tasks that may aid your understanding:

1) Play around with the attached circuit simulation. Look at the voltages across the capacitor and the resistor and compare the information to your knowledge from Topic 5. 

2) This Desmos graph of voltage/charge/current has sliders for voltage, capacitance, and resistance. Note the relationships between the shapes of the curves and the discharge time as you manipulate the values. You can also do this with your graphing calculator any time.
