In a common-base transistor, α = 0.95 and the emitter current is 1 mA. The collector current is:

Answer: 0.95 mA.

A 1.05 mA
B 0.95 mA
C 0.05 mA
D 1.00 mA

Correct answer: B. 0.95 mA

Explanation: I<sub>C</sub> = α I<sub>E</sub> = 0.95 × 1 mA = 0.95 mA.

Conductors have overlapping bands, semiconductors have a small energy gap that can be bridged by heat or doping, and insulators have a large gap that blocks conduction.

Concept context

Band theory, p-n junction, diodes, transistors, logic gates, and integrated circuits.
