The voltage across R2 = + 10 V mean VB=10V then how the hell VE=0.7, VBE=VB - VE =0.7?
answer also, VB-VBE-IE*RE = 0.
answer also, VB-VBE-IE*RE = 0.

How the value of Ve will be 0.7,as the voltage across R2 means it's base voltage, means Vb is 10V, and given Ve 0.7,then the value of Vbe will be 10 - 0.7 i.e. 9.3.

VR2 - Vbe - ieRe = 0.
Substitute in this formula you will get an answer.

@Ahakash.
The voltage across emitter is 9.3volt not 0.7.
The voltage across emitter is 9.3volt not 0.7.
