The transistor in the given circuit should always be in

The transistor in the given circuit should always be in active region. Take V_{CE (sat)} = 0.2 V. V_BE = 0.7V. The maximum value of R_c in Ω which can be used, is ______

In B-E loop, using KVL, we have
5 – 2KI_B – V_BE = 0

⇒ I_B =	5 - 0.7	= 2.15 mA
	2K

and I_C = βI_B = 100 × 2.15 mA = 215 mA
Using KVL in C-E loop, we get
V_CE = 5 – 0.215 R_C
For active region, V_CE > 0.2 V
⇒ 0.215 R_C < 5 – 0.2

⇒ R_C =	4.8	≅ 22.32 Ω
	0.215
