 In a BJT, if the collector-base junction is reverse-biased and the base-emitter junction is forward-biased, which region is the BJT operating in?

Detailed Solution for Test: BJT Configuration - Question 3

If the collector-base junction is reverse-biased and the base-emitter junction is forward-biased,then the BJT functions in the active region of the output characteristics.

Test: BJT Configuration - Question 4
Save

In a BJT, if the collector-base junction is forward-biased and the base-emitter junction is forward-biased, which region is the BJT operating in?
Detailed Solution for Test: BJT Configuration - Question 4

If the collector-base junction and the base-emitter junction are both forward-biased,then the BJT functions in the saturation region of the output characteristics.

Test: BJT Configuration - Question 5
Save

In a BJT, if the collector-base junction and the base-emitter junction are both reverse-biased, which region is the BJT operating in?
Detailed Solution for Test: BJT Configuration - Question 5

If the collector-base junction and the base-emitter junction are both reverse-biased,then the BJT functions in the cutoff region of the output characteristics.

Test: BJT Configuration - Question 6
Save

From the given characteristics, what is the value of IC at IB=30 uA and VCE=10 V?
Detailed Solution for Test: BJT Configuration - Question 6

At the intersection of IB=30 uA and VCE=10 V, IC=3.4 mA.

Test: BJT Configuration - Question 7
Save

 From the given characteristics, what is the value of IC at VBE=0.7 V and VCE=15 V?
Detailed Solution for Test: BJT Configuration - Question 7

From the characteristics, the value of IB at VBE=0.7V is 20uA. Now, from IB=20 uA, we get IC = 2.5 mA.

Test: BJT Configuration - Question 8
Save

 Which of the following correctly determines the relation between α and β?
Detailed Solution for Test: BJT Configuration - Question 8

α and β are related as β=α/(1-α).

Test: BJT Configuration - Question 9
Save

The value of IC is precisely zero when the value of IE is zero.
Detailed Solution for Test: BJT Configuration - Question 9

 When the value of IE is zero, then the value of IC is equal to ICBO which is in the order of microamperes but not zero.

Test: BJT Configuration - Question 10
Save

For common emitter configuration, which of the following is the correct relation?
Detailed Solution for Test: BJT Configuration - Question 10

All the relations hold true i.e. IC = βIB and IC = αIE. As α<1, hence IC < IE
