About

An essential foundational course for study of electric circuits at any level. Learn how to: - Use analogies to understand resistance, current strength, potential and potential difference. - Know how to measure these variables. Explain the role of cells as energy sources in electric circuits. - Use a simulation to investigate the effect of adding cells in series and parallel. - Investigate the effects of length and thickness on resistance. Apply this knowledge to explain how a polygraph (lie-detector) works and debate whether its readings are trustworthy.
