Basic electronics - the diode
OK, we're trying to cover the basic components of radio circuits in order to get to grips with the heavier stuff to come - circuit diagrams etc.
I tried Wikipedia for a definition of a diode, but it was a bit long-winded. Because I'm new to this stuff, and because many of you will be too, I prefer straightforward descriptions to help us more easily understand what these wee things do.
After a very quick websearch, I found the following from this website:
Diodes allow electricity to flow in only one direction. The arrow of the circuit symbol shows the direction in which the current can flow. Diodes are the electrical version of a valve and early diodes were actually called valves.
More later . . .
