OH GOD

YAH OH GOD I KEEP PRESSING THE ENTER BUTTON AFTER TYPING THE TITLE!!!!
Bad habit lol.

Anyway, as i was saying, I have a marvellous idea of revising your homework and having fun at the same time.
Ok maybe practise(or practice) our homework. Normally when we practise like maths or something we would need to do our working on a piece of paper or something. Waste paper, pencil lead(graphite i guess if what that is called), maybe a bit of eraser. Also, a bit of wrist pain after writing long stuff.
But since the invention of computers+ internet = blogs as a small part of this new age...



Why not use blogs as our personal practice book or jotterbook or whateveryoucallitman!



Haha yeah what i mean is use our blog as a practice book! Haha.
Nothing else to say, so I'll start my damned homework lol.
Today I learnt analog electronics, electrical science, germ and that computers in the "E-learning lab" are really good.



I was trying to be sarcarstic on the latter comment. Lol.





Analog electronics- )> With AC comes DC. I mean AC can be converted into DC. Anyway, The formula for converting AC into DC is Vdc=0.318(Vpk).
That was a Half wave rectifier. Because diodes are used in the process of converting AC to DC, diodes are only one-way so when the current goes from the negative side nothing goes through the load(by load meaning the output or whatever u want it to be). Waste of energy.
Luckily, there is a full wave rectification. Very easy. Make a bridge connection consisting of diodes, where each pair faces a different direction. The load is in the middle of the bridge. This way the current that goes through the positive and negative terminals can be converted into DC and pass through the load or go into or whatnots.
The formula is kinda simple- 0.318= half wave, so full wave= 0.318 x 2 = 0.636(Vpk). Haha.

Electrical principles- )> Vectors, when calculating against gravity, gravity can be taken as
-10m/s^2. Similiarly when working with gravity(free fall or something) gravity is 10m/s^2. My class and lecturer got kinda confused over it and how to explain it lol.
Germ -
0=null
1=eins
2=zwei
3=drei
4=vier
5=fünf
6=sechs
7=sieben
8=acht
9=neun
10=zehn
11=elf


elf lol.
