In the given figure, given that VBB supply can vary from 0 to 5.0 V, , The minimum base current and the input voltage at which the transistor will go to saturation, will be, respectively :
25 and 3.5 V
25 and 2.8 V
20 and 2.8 V
20 and 3.5 V
Relation between emitter current ,Base current,collector current -
- wherein
At saturation
We known that
So
So
25 and 3.5 V
Option 2)25 and 2.8 V
Option 3)20 and 2.8 V
Option 4)20 and 3.5 V
