The p-n-p transistor circuit as shown in the above figure is in saturation. Given that V_BE = 0.7 V and V_{CE (sat)} = 0.3 V and β_min. = 20, the value of I_C will be—

1. 4.7 mA
2. 5.3 mA
3. 8.6 mA
4. 10 mA

Correct Option: A

Given V_BE = 0.7 V, V_{CE (sat)} = 0.3 V, β_min. = 20,
R_C = 1 kΩ, I_C =?

I_C =	V_CC – V_{CE (sat)}
	R_C

or I_C =	5 – 0.3	= 4.7 mA
	1 kΩ

Hence alternative (A) is the correct answer.
