In An Npn Transistor The Collector Current Is 24 Ma Physics QuestionIn An Npn Transistor The Collector Current Is 24 Ma Physics Question

In an NPN transistor the collector current is 24 mA. If 80% of the electrons reach collector, its base current in mA is

Options

(a) 36
(b) 26
(c) 16
(d) 6

Correct Answer:

6

Explanation:

Since 80% of the electrons reach the collector, 20% only remain.

Base current = (20 / 80) x 24 = 6 mA
