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 is lower then 0.7V. I know all the math and theory behind that, but i want to be able to understand that on the verry basic scale. I mean like when you explain what heat is and you say that heat is the friction of the atoms caused by let's say a passing electron flow.
