I can't quite get my head round the fact that when a voltage is applied to a circuit electrons travel from negative to positive causing current flow but current flows from positive to negative. Can't visualise it.

Anyway I've enrolled in for an OU course. (STEM degree). Last time I did something like that I caused myself so much stress as didn't really have the time or motivation to do it. Anyway that was a good few years ago. Giving it another go. Or could just be my state of mind at the moment making me do impulse things. Usually my impulse thing is to buy then sell my motorbikes.

I haven't been out on my bikes for ages, I used to go for joy rides in all weather but I just can't get the motivation at the moment which is unusual. Not riding affects my state of mind, I'm sure of it.

My relationship that has lasted more than 2 years now. I remember posting here the time I met her. It was fucked up then as it is now. 2 years not one argument, sounds good, it's not. And is.

My understanding. Could be wrong because you usually reach a certain level of understanding that explains what you're seeing then when you move up to the next level of understanding, it's shown to be not the whole story.

Electrons don't actually flow as such. One electron doesn't go round from one end to another, they more kind of sit in a big swirling cloud in the metal and when you apply a potential difference they rearrange themselves so there are more hanging about mostly at one end of the wire than the other.

Electrons carry a negative charge so the end nearest the negative is more negative and the end nearest the positive is more positive so you put the positive end of an ammeter at the positive. We've chosen to call that directionality positive current flow. Older motorbikes are positive earth so you'll get a big shower of sparks if you connect the negative to the frame by accident

Cathode ray tubes would suggest the electrons do flow....

I signed up for the great courses on Amazon Prime. Going to work my way through the science and engineering ones. Started on Electrical Engineering for Everyone. Good starter course.

I have an HNC in Electrical and Electronic Engineering from 1991. At that time I wasn't interested in the course just the HNC at the end of it. Things have changed dramatically in that field. It's easy to just google for expalanations of scientific principles. Some I could potentially get my head around. More not. It's just this electron flow/current flow that's bugging me right now lol I remember Flemings laws from from 1991 which kind of explain current flow, but not why there is current flow, still don't get it. Electromagnetic fields and energy. Energy can never be created or destroyed, just transferred was something useful I learned today though

Stinkwheel In my head Electrons carry negative charge but are attracted to the positive charges (Protons), like a magnet attracts opposites). This happens when an electron escapes one atom and is attracted to the proton on the next atom along that has lost an electron.

Next thing is how a potential difference is created? Electromagnets. What actually is a magnetic field. lol

This is the only forum in the universe that I post in. You guys get it all whether you want it or not.

[stinkwheel]

In metal solids, the electrons aren't really bound to the individual atoms, they kind of swarm around. There are the correct number of them but they aren't held tightly and can be knocked around by electromagnetic forces. Which is why metals conduct electricity.

A sharp metal point will have a slight negative charge even without applying a potential difference.

Or such is my level of understanding.

Understanding the Quantum realities of electricity seems like a big ask

BTW So called 'conventional current' evoked through someones bad guess (might be Fleming again) goes the opposte way to the electrons. Just in case you weren't confused enough.

Oh fucking dear. No the stand wasn't on the grass when I left it. It was windy like I've never seen before. If I'd been sensible I'd have taken the cover off. Worse than it blowing over is that the exhaust is rusty underneath.

Oh well only a few scratches.

Really enjoying the OU course. Started with chemistry and learning a lot. Last time I did chemistry was in second year at school in 1981.

Two things I need rid of soon

1. CBR400RR-R
2. Girlfriend, 'partner' or whatever it is these days, used to just be girlfriend. Anyway his is the text I sent to initiate the conversation. I like her a lot and genuinly just want her to be happy just basically can't be bothered and genuinly think she's be better off without me I am passed all that relationship stuff and have my dogs

Here it is I feel shit. She doesn't deserve it after over two years of it.

"Why do you still want to stay with me? You know what I am like and that is never really likely to change. I can't believe you couldn't find someone more suited, younger, not an addict. Someone to be intimate with that you can have a future with. I am not a good choice for you. I like you so much and would be happy if you were happy. I understand if you wanted to be 'friends' Oh fuck knows. Just feel bad about the whole thing."

Actually wish I'd never sent that. Just waiting on a phone call, wish me luck

Well that's it done. I haven't cried since about 1972. Never even when my wife died. I care for this lady a lot.

She lives a fair bit away 35 mins in the car. Her son is 15 and causing her all kinds of bother so she won't leave him at the moment, she used to come every weekend. I have a disabled son so I am a bit tied up at home most of the time. Also I am lazy and don't make enough effort.She works all sorts of shifts. Means we have been seeing each other less and less. It's been dropping down a gear for a while really.

[A100man]

[struan80]

Turns out I'm devastaed never realised how much I liked her. Gone from 4 video chats a day to nothing. Hard to get used. Turns out I love her but it's all over now. It's for the best and had to happen sometime, she's 20 years younger an has her life in front. Better off without me really.

[A100man]

[struan80]

Acht well all good I'm just about over it, was only a matter of time and it's best.

More distressing is that I need to sell my CBR400 RR-R.

[A100man]

[struan80]

Then you spend your benefits on 2g of coke. I get single person's allowance and unable to work allowance. My son get pip and single persons allowince. I am fulltime carer, he's 21. Life is restricted a little bit. He's all buggered up in so many ways.

Life is good until tomorrow

Have the 400 up for sale. Lots of messages and most full of shit. Anyway it'll sell soon enough.

Not been out on a bike for ages. Hopefully the weather will get better so I can do my old man on a sportsbike thing.

[P.]

Are you still running the 250?

[struan80]

Hope you get a nice sale here, it looks really clean.
