Hi everyone,

I didnt decide on what i specialyse my blog now but it will happen in the next 2 days... hopefully.

I'm also feeling totally sick because i thought it would be a good idea to drink with friends, sleep 3 hours and then go to work.

Never gonna do that again. I felt like i have to puke all the day and the headache is killing me. Im going to bed very early today.

But first, I'll tell you how voltage and current are acting on components that are "parallel".

Personally i find "parallel" harder to understand than "in series" because... well, you will see.

Q:

When are components "parallel"?

A:

Two components are parallel if both input wires and both output wires are connected.

Q:

How are current, resistance and voltage acting in this shit?

A:

Its like the opposite of "in series". Here is the voltage the same. These 2 resistors are like 1 resistor with another resistance.

The whole resistance is always smaller then the smallest resistor. (WHAT?)

Look, the current splits itself based one the resistance of each resistor.

Its like you got one street where cars are driving through. If you build another street around the first one, the second street may be longer but together with the first street there can drive more cars.

cars = current

street = resistor

Calculating the whole resistance is a little tricky. There are 2 formulas to calculate.

1/R = 1/R1 + 1/R2 + 1/Rx

or

R = (R1xR2) / (R1+R2)

I prefer the first one because its easier to understand, you can calculate the whole resistance in one formula and its easier to tip into my pocket calculator ^^

If you didnt understood that, this picture maybe will help you

You dont understand the last calculation-step? Look, you can multiply, divide, add or subtract each side with the same number and the result will be the same. Try it.

Example:

1 = 1 (true. now adding 5 to each sides)

1+5 = 1+5 (still true, now dividing through 3)

6:3 = 6:3 (damn, still true. weird math shit)

In the last calculation step on the picture, our fomula looks like that:

1 : R = 0.000325 (now multiply each side with R)

1 : R x R = 0.000235 x R (divided through R and multiplied with R lift each other & now dividing through 0.000235)

1 : 0.000235 = 0.000235 : 0.000235 x R (0.000235 : 0.000235 = 1. R multiplied with 1 is R)

1 : 0.000235 = R

R = 3076,92 Ohm(like i said, crazy math shit)

Summarized:

- Voltage the same

- current splits and get back together

- resistance always smaller than the smallest resistor

By the way, if you got 5 seconds more to waste, vote on the right side if i should talk some german in the future ^^

Bye :D

it all comes back to memory very fast :)

AntwortenLöschenWell I've learnt something new from this post, thanks.

AntwortenLöschenI loved the way you explained this. :)

AntwortenLöschenIf i tried to do that i would end up electrocuted :(

AntwortenLöschenyou blow my mind haha

AntwortenLöschenWow, really great explanation, thanks for taking the time to write that... and as far as specializing your blog, i'd prefer it if you kept it random and interesting, rather than having to focus on one subject!

AntwortenLöschenYou explained it very well.

AntwortenLöschenI had to make a house, with all that stuff, in parallel and in series.

If you had posted it before, I would certainly use it in this job.

too much math to my head :P

AntwortenLöschenAlways a great explanation

AntwortenLöschentrue that @Diego Sousa :D

AntwortenLöschenDude, don't go German. You're doing just fine the way it is.

AntwortenLöschenThis is a great explanation! Looking forwards to more!

AntwortenLöschenimpresive stuff..nice post...nice blog btw, check my out

I didn't vote since there was no middle ground. I could see it sprinkled here and there though. Just little enough that english speakers can comprehend :P

AntwortenLöschenJust learend that in school before summer :P

AntwortenLöschenNever learnt this, mostly because I dropped science in school haha. bad me.

AntwortenLöschenOh this brings back traumatic memories of physics class....

AntwortenLöschenI always hated this part of physics

AntwortenLöschenLooks too confusing for my tastes. Nice blog man.

AntwortenLöschenHang overs suck, good explanation though!

AntwortenLöschenMan this was confusing, but i think i got it?

AntwortenLöschenI remember learning some of this in High School. Hella cool..

AntwortenLöschenYay, following now!
