Practical Considerations,When dealing with electronic equipment there is no substitute for practical experience. Every opportunity should therefore be taken to extend one’s capabilities in this respect. For most readers of this book there are two aspects to consider, namely, the building of equipment, and the servicing and maintenance of electronic apparatus.

Each electron carries a small negative charge (1•602×10–. coulombs) and when many millions of them flow along a wire a charge . will pass a particular po

In the early days of radio and electronics the necessary power was derived from batteries, but the large currents and voltages required for thermionic valves made this source inconvenient. Leclanché type batteries were bulky and expensive, and the lead-acid accumul
