Question
The ideal BJT in the circuit given below is biased in the active region with a of 100. If is , then (in Volts, rounded off to two decimal places) is _______ .
Correct answer
(C) 1.92
Solution
Given and , we have .
The emitter current is .
From the circuit diagram, the resistor is connected to the collector node. This is a collector-to-base bias configuration. The current flowing through the collector resistor is the sum of the collector current and the base current: .
Applying KVL in the output loop:
.
Thus, the correct option is (C).
