capacitors – charge, energy and graphs

We’ve just completed the topic on capacitors in dc circuits, finishing off with a detailed study of the graphs obtained for current & voltage against time when a capacitor is charged or discharged through a series resistor.  There are some additional notes and practice questions at the end of this post but please watch the clips first. This introduction to… Read more »

input devices in a voltage divider

This powerpoint file from the High School of Glasgow summarises the function of different electronic components and explains their use in common voltage divider circuits.  There is a pdf version of the file below.
