In NPN transistor, 10 10 electrons enters in emitter region in 10 –6 sec. If 2% electrons are lost in base region then collector current and current amplification factor ( β β ) respectively are
Text Solution
Verified by ExpertsThe correct answer is:
A
Since 2% electrons are absorbed by base, hence 98% electrons reaches the collector i.e. α α = 0.98
⇒ ⇒ 
Also current amplification factor
