if i think of a bipolar trnasistor, it has 3 areas.p,n,p or n,p,n that means that they are like 2 diodes connected with the anodes or cathodes together....
but in real life if i connect 2 diodes like this, do they work as a transistor?
and another thing about tolerances....
lets say.....if i got a resistor with a 2% tolerance and one with 5%, 2K and 3K. i connect them in series. i get a resistor 5K, with what tolerance?
2000*0.98=1960; 2000*1.02=2040
3000*0.95=2850; 3000*1.05=3150
so i will have a resistor with the value of 4810-5190, wich means 5K+190R/-190R so i get 5K+/-3.8%
am i right?
and if i have them in paralel......a littel bit more complicated, but do i have it right since now? if yes, then ill continue with the paralel.
