VCE Physics Unit 2: Option 2.4: How can AC electricity charge a DC device?

Year 11 Research Guide for Unit 2 Physics

Option 2.4: How can AC electricity charge a DC device?

This option investigates the processes involved in transforming the alternating current delivered by the electrical supplier into low voltage direct current for use with small current electrical devices. Students investigate a variety of circuits to explore processes including transformation, rectification, smoothing and regulation. They use a variety of instruments to observe the effects of electricity. 
On completion of this unit the student should be able to construct, test and analyse circuits that change AC voltage to a regulated DC power supply, and explain the use of transducers to transfer energy. 

240V AC to 6V DC

The video below is a lecture by Prof. Walter Lewin on Electromagnetic Induction, Faraday's Law, Lenz Law, Complete Breakdown of Intuition, Non-Conservative Fields.

The actual lecture begins 5 minutes in, but there is some sound advice given in those first 5 minutes.
