Analog Electronics - Engineering

Q1:

The collector voltage VC of the circuit shown in the given figure aside is approximately

A 2 V

B 4.6 V

C 8 V

D 8.6 V

ANS:B - 4.6 V

Option B is correct.

Because vc=vcc_ICRC OR VE+VCE;
VE=VB_VBE VB=(RB2/RB1+RB2)VCC VBE CUT IN VOLTAGE 0.7 AND VCE CUT IN VOLTAGE 0.3.
