This is a set of 20 multiple choice questions covering electricity, circuit symbols, series and parallel circuits, basic reading of an ammeter and prediction of the brightness of bulb in different ...

This is for pupils looking at circuits around year 7. It is suitable for KS3 and ISEB common entrance. It reviews/introduces basic circuit symbols and then has different circuits to make to compare ...

For reliability, designers must create flex circuits that are neither too thick nor bend too much. • Every flex circuit has a neutral-bend axis. • Smaller circuit thickness reduces the risk of damage ...

A resonant circuit is formed when a capacitor and inductor (coil) are in parallel or in series. The two circuit elements will block or pass a single specific frequency out of a divers mix. For this ...

You're probably familiar with the old-fashioned strings of holiday lights that go out completely if one bulb burns out. Although these lights cause hours of frustration during the holidays, they also ...

Switching algebra is easily visualized using switches since there are only two values: on and off, or true and false. In digital systems we represent these as 1 and 0, respectively. There are only two ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

This module covers the fundamental ideas underlying design of modern digital systems. This module explains the basis of circuit elements, how they are interconnected to form digital circuits and also ...
