Interactive GCSE Electronic Circuits

A powerpoint with animations demonstrating the operation of a number of basic circuits. Ideal for lazy starters and plenaries as well as general teaching. Slides progress by key-press to allow for directed questioning. The file is editable to your own needs.

Potential dividers - Introduction to formula and three worked examples
Potential dividers - Animation shows the voltage produced at the wiper of a potentiometer
Light Dependent Resistors: Animation shows the output voltage produced as light level changes
Comparator: Animation shows the effect on the output level for combinations of input levels
Light Sensor: An animated description of the operation of an op-amp based dark activated switch circuit
555 Timer (Astable): Formula introduced and an animation shows the effect of changing timing capacitor value
555 Timer (monostable): Formula introduced and an animation shows the basic operating principle
FET Driver: Single page simple explanation of a FET
AND Gate: Animation showing the effect of changing input levels using a switch analogy and plotting a truth-table
OR Gate: Animation showing the effect of changing input levels using a switch analogy and plotting a truth-table
