MHT CET 2023 Physics question
Not in JEE Advanced syllabus
In an n-p-n transistor, the collector current is 28 mA. If 80 % of electrons reach the collector, its base current in mA is
Answer: (D)
Solution
In a transistor the emitter current is . If 80% of the electrons from the emitter reach the collector, , so mA. The base current is mA, option (d).
