In an NPN transistor the collector current is 24 mA. If 80% of the electrons

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
