One of the more fascinating applications of electricity is in the generation of invisible ripples of energy calledradio waves. The limited scope of this lesson on alternating current does not permit full exploration of the concept, some of the basic principles will be covered. ...

Our first three chapters are based almost entirely on A-level mathematics, while the next five require little else beyond some elementary group theory. It is only in the last three chapters, where we treat more advanced topics, including recent developments, that we require greater mathematical ...

In theory, then, AC can be used to operate a DC relay. In reality, however, doing so is impractical. Since alternating current decreases to zero every half-cycle (120 times per second for 60 cycle voltage), the relay armature tends to release every half-cycle. Th...
protective earth (in theory N = PE). An external instrumentation amplifier computes the difference between Pi and N. I could add a 3-to-1 analog mux in front. Mains voltage being scary I've added a fuse, a MOV and a resistor but I'm not sure if they are all necessary (or ...
