In the following circuit, the transistor is in active mode

In the following circuit, the transistor is in active mode and V_C = 2V. To get V_C = 2V. To get V_C = 4V, we replace R_C with R'_C. Then the ratio R' _C / R_C is ______.

we have V_c = 2V;
Now, I_c R_c = 10 – 2 = 8 ...(i)
We have V_c = 4V
and I_c R_c = 10 – 4 = 6... (ii)

	I_c R_c	=	6
	I_c R_c		8

∴	R_c	=	3	= 0.75
	R_c		4
