23 Capacitors

This page covers the capacitors section of the course.  One crucial part of this section is the ability to understand how to take Ln on an expoential function. You must make sure you work this out before you start the decay part. Also there are some tricky formulae again so you must make sure you make notes and go back to them to check what each thing is and when it applies. A capacitor has a current which changes all the time (unless charged with a constant current) so the formula are all time based.

Natural Logarithms

This algebra video tutorial provides a basic introduction into natural logarithms. It explains how to evaluate natural logarithmic expressions with the natural base e and how to evaluate exponential ...expressions with natural logs in on the exponent of the natural base e using properties of logarithms.

Theremin Prague Museum of Music – Capacitors!

Theremin Prague Museum of Music The theremin was the product of Soviet government-sponsored research into proximity sensors. The instrument was invented by a young Russian physicist named Lev Sergeyevich Termen (known in the West as Léon Theremin) in October 1920 after the outbreak of the Russian Civil War. After a lengthy tour of Europe, during which time he demonstrated …
