What Is Charge?
Even if we stop asking about "electricity," we still must ask about
Charge.
What Is Energy?
Even if "electricity" isn't a form of energy, WHAT IS ENERGY? Is it like
a substance, or is it just an abstract concept?

HIGHLY RECOMMENDED BOOKSBooks, but also one website. Paul F's circuit simulator does what I've always dreamed about: uses the "charge flow" concept to animate a complex circuit without needing any hardware. The slow charges move along, and the wires' surface charge appears as changing red and green!Paul Falstad's Java circuit simulator Since the 1980s, K12 textbook offerings have been improving. When I first started these articles in 1986 I could find no text that wasn't choked with mistakes and misleading concepts. But during the time I lectured on the problem to teachers in MA, the late Dr. Mel Steinberg at Smith College (also in MA) was working on a solution: Genecon generators and supercapacitors. His C.A.S.T.L.E. highschool curriculum, Capacitor-aided System for Teaching and Learning Electricity, is designed to directly attack typical student misconceptions in electricity. A curriculum: C.A.S.T.L.E Project (also kit of parts) A textbook: Electricity and Magnetism ( also teacher's ed) A textbook: Electrical Energy and Circuit Design ARTICLES LISTED BY POPULARITY |
