Home » Analog Circuits » Analog circuits miscellaneous » Question

The transistor used in the circuit shown below has a β of 30 and I_CBO is negligible.

If the forward voltage drop of diode is 0.7 V, then the current through collector will be

1. 168 mA
2. 108 mA
3. 20.54 mA
4. 5.36 mA

Correct Option: D

Transistor is in saturation region

∴ I_C = -	12 - 0.2	= 5.36 mA
	2.2K
