6.30 A very simple circuit for measuring β of an npn transistor is shown in Fig. P6.30. In a particular design, V CC is provided by a 9-V battery; M is a current meter with a 50-μA full scale and relatively low resistance that you can neglect for our purposes here.Assuming that the transistor has V BE = 0.7 V at I E = 1 mA, what value of R C would establish a resistor current of 1 mA? Now, to what value of β does a meter reading of full scale correspond?What is β if the meter reading is 1/5 of full scale? 1/10 of full scale?
