This one gets us a bit further along the road to nowhere (famous last words of a lemming) and still on the same track as the Selmer blog.
As an electronic power source, this shape of voltage is useful to man nor beast. It might pass muster as something that would charge a battery, or as source of electrocution. (If that’s what turns you on. So to speak.)
1) I was drunk when I drew it.
2) My pencil slipped.
3) This computer wants to see me dead.
You got to admit that that is not a very long list of excuses. But I ‘m not a politician. If I was, I could fill a complete hard drive with them. My team of excuse manufacturers would have field day and ‘brainstorm’ until they drowned in the monsoon. Yes, I know, it’s a forlorn hope.
And now, back to the plot. I think I left it in the back of this drawer somewhere………..
The major difference between the top diagram and the lower one (That’s not counting that they’re as similar as a stoat and an octopus) is that the top one has one nobbly-thing (technical eh?) and the bottom one has two nobbly-things AND A LINE. I could (were I in full possession of a brain cell) just keep repeating the upper drawing and I would get a lot more of the same thing. That’s more of the technical stuff, of course.
If the long-suffering reader would care to look down a bit, that’s instead of staring at the ceiling and wondering when it will all end (‘lay down and think of England’ about covers it. Or Brazil. Or Australasia.) he/she will notice that at A, which looks a lot like A in the last blog, there is a subtle difference. That partly to demonstate that I can in fact spell ‘subtle’ and partly to introduce a component called a ‘Capacitor’. The capacitor is labelled ‘C’, ingeniously. It is this single component that can convert the unusable voltage in the top diagram, to the almost unusable diagram underneath it.
The Line X-Y on the lower diagram is an approximate discharge path for the capacitor.
“So what?” you might well ask. That’s where I can tap the side of my nose and do my Ron Moody impression in ‘Oliver’. Or was it ‘Fiddler on the Roof’. One of them, anyway.
This leads (onwards and upwards) to explanations of what a capacitor is, what it does and how it does it.
It also leads to me getting a cup of tea, and you not. Nothing personal you understand.
