Physics Question on Transistors

The given transistor operates in saturation region then what should the be value of VBB:(Rout=200Ω,Rin=100KΩ,VCC=3volt,VBE=0.7volt,VCE=0,β;=200)V_{BB}: (R_{out} = 200 \Omega, R_{in} = 100 K\Omega, V_{CC} = 3 volt, V_{BE} = 0.7 volt, V_{CE} = 0, \beta; = 200)

A

4.1 volt

B

7.5 volt

C

8.2 volt

D

6.8 volt

Answer

8.2 volt

Explanation

Solution

V = V - I R ⇒\Rightarrow 0 = 3 - I ??200
