QNEET-2022-Ph-536: NEET 2022 Physics - Class 12 NEET-2022-Ph-536 Solution: The collector current in a common base amplifier using n-p-n…
The collector current in a common base amplifier using n-p-n transistor is 24 mA. If 80% of the electrons released by the emitter is accepted by the collector then the base current is numerically: 3 mA and entering the base 6 mA and leaving the base 3 mA and leaving the base 6 mA and entering the base
Multiple Choice Options
- A 3 mA and entering the base
- B 6 mA and leaving the base
- C 3 mA and leaving the base
- D 6 mA and entering the base
Step-by-Step Verified Solution
Given I C = 24 mA
_ = 0.8 = I C I E
I E = 24 0.8 mA = 30 mA
I B = I E _ I C = 30 _ 24
= 6 mA, entering the base
