Oooh, i think i get it now:-D. Not so long ago i searched the internet for explanation on how charhed particles get their charge.. only to find later that this wasnt yet explained by science. We live in a such era, that we use basic laws (Ohms law for exam) that were invented long ago, and...
Good question, CWatters! Apperantly all resistors are in nature still conduct. In order to conduct, they must have loosely held electrons. As a resistance grows, it gets harder and harder for these electrons to break, until atlast, in nonconductive materials there are no free charges. Current...
Oops, sorry i write that twice, but i am new here and clicked the wrong thing the first time:-D. Thank you for youre answer, it really helped me out :-)
Homework Statement
A voltage divider with two resistors R1 and R2 is given. The output is connected to a transistor so VB is always equal to the base emitter voltage=0.7v.
Homework Equations
How can i explain physicaly (wath happens to the electron flow and such) why when R1 is verry high, VB...
