Bipolar Junction Transistors (BJT) - Technical MCQs

Q1:

A decrease in base current of a C-E amplifier causes the voltage measured between the emitter and the collector to increase.

A True

B False

ANS:A - True

as we know the Vce= Vcc-IcRc, where Vcc is dc power supply and Ic is collector current, Vce is the voltage across collector and emitter or output voltage. And also Ic=BIb(B=Beta). As Ib increases Ic will also increase i.e. Vce will decrease.
