new post, new infos

Hi there,

so today i dont have that much time to write a post where you have to scroll 5mins to reach the bottom.
So im going to make that quick and finish the electronic basics.

Frequenzy:
The amount of how many times something happens in 1 second.
For Example:
Your heart beats, if you are relaxed, around 1 - 1.2 times per second.
To know the frequenzy you have to divide 1 through the seconds.
Example:
In my country (i dont know if this is everywhere in the world) the sinus wave of the voltage of my power socket has 50 Hertz.
Now we know that the sinus wave repeats itself 50 times each second.
To know how long 1 sinus wave takes, we have to calculate like this:
t (time in seconds) =  1 /  F (frequenzy in Hertz)
t = 1 / 50
t = 0.02 seconds (20milliseconds)

If you put your finger into the power socket, the current is not the worst that will happen to you. You may have some burnings but the frequenzy is way more dangerous.
Because the current is higher than your body signals, it will force your heart to beat 50 times each second!
Believe me when i say: You wont survive that for to long.

Now i maybe scared some of you guys off from current, voltage and resistance but thats just what i wanted. I think its better to first scare you before i will tell you what you can do with the knowledge you now have. (its not much but enough to do some things).
If i told you from the beginning "oh, its so great you should try that too. so easy, so fun." Some of you may have had hurt themselfs because they were to thoughtless.

Next time... dont know, you have to wait and hope it will be something interessting ^^
bye :D
