Yeah. Don’t understand the figure at all.
This was first question of Mt2 ? I didn't understand, but did some jugaad to get 250
Did you see Solution ?
If I assume Ie≈Ic then even I'm getting 250
Yes , they also did assume it
Can anyone of you write and show?

It's Base-collector resistance
Which is high, that means that approximation is valid, and e-h pair recombination is very low, Ib tends to 0
