Example 14 9 In Fig 14 31 a the VBB supply can be varied from OV to 5 0 V The Si transistor has Bac 250 and R 100 kn R 1 KQ Vcc 5 0V Assume that when the transistor is saturated V OV and VBE 0 8V Calculate a the minimum base current for which the transistor will reach saturation Hence b determine V when the transistor is switched on c find the ranges of V for which the transistor is switched off and switched on
