In an NPN transistor circuit the collector current is $10 mA$ . If only 90% of emitted electrons reach the collector, then (to the nearest mA)

Answer:

Solution:

Ninety percent of emitter current reaches the collector.

$I_{C} = 0.90 I_{E}$

$I_{E} = \frac{10}{0.90} = 11.11 mA \approx 11 mA$

The nearest stated value is C.
