How to : solve resistor warming case mathematically

A magnetic coil, which made from copper have constant voltage. In operation the temperature is going higher from 12 degrees Celsius to 60 degrees Celsius. How much percentage has the electric current changed by the warming of the coil?
bonus. how much is the percentage of the resistor?
What we know?
voltage is constant
This function about how to search resistor from a certain temperature

= Resistor from temperature theta
= Resistor from referenced temperature
= coefficient from temperature which depend on the material
= referenced temperature (in most case 20 degrees Celsius)



what do we need to calculate


okay here is the answer


that is the way to search the resistor's percentage

then move to electric current


with that we can search for the percentage

thats all. 19% change on resistor and 16% on Electric current.

  • use Latex for this mathematic calculation
  • thanks to codecogs for letting me write latex on blogspot
  • i use lyx to get better view of what i calculate
  • it also give me another project about how to install latex plugin on Ubuntu

Transfer Project 2010 part 4 : Final

one of the best
When you read this post, that mean another person on this world join with one of the best os in the world. 
Anyway as you read this, my computer is running on ubuntu. one of the linux distribution, perfect for newbie just like me. backup is the time wasting part on this project. i have thousand unarranged file on my wubi and window xp and i have to move this on my external harddisk and maybe move it back to this computer.
not only with file management, software and driver also give me more weight on this problem. i already tested new pro evolution soccer 2011 but it didnt work because my old computer spesification. next problem is also the setting on my cairo dock. i have make it from the very beginning. the last problem significant problem is the look of my ubuntu. i have already change the windows style and icons on appearance but because i forget how i change the appearance on my wubi, i didnt feel my new ubuntu look better than the last.
what help me most on this project is internet. yes, internet. i dont need any other people to set up my computer or to ask, because i already have internet. luckily my place got a decent internet speed, so i dont get let down on this project. I warn you. if you want to change to ubuntu, you have to have a real computer management on everything. just like what software do you want to use? what must i need to do this or that? is there specific file that i need? if you can answer those question, there is still another question. so dont worry.
migration process is quite a hastle but thanks for this post i can get it through. the command isnt always working so if you fail just copy it just like you always do. on my migration not all command cant work so did manual labor, file managemen through nautilus. the back on source is working but cant back up everything. make sure you read till the end, because there is a good comment about how to not download everything.
on ubuntu i need few things from my old windows. just like my langenschiedt e-dictionary. its little bit tricky. what do you need is wine and q4wine. both is already on software center so just search this name. open q4wine and go to wine icon on setup tab. click 'install winetricks' to get list of essential windows application for wine. after that you have to search for 'vcrun2005' and click 'install'. after installation go to your langenschiedt folder, install the font on 'fonts' folder on  and run 'ew_lkg.exe' with wine. that should do the trick. that also work for byki. the step is almost the same but now you have to search for 'msls31', 'urlmon' and 'riched20' on winetricks.
detailed explanation will be on another post. 

ps note of the week dont microwave you chocolate-filled donut. it just doesnt work that way.
