Question

In an n - p - n transistor circuit, the collector current is 10 mA . If 90 % of the electrons emitted reach the collector, The base current will be 1 mA, The base current will be -1 mA, The emitter current will be 9 mA, The emitter current will be 15 mA

As I C = 90 % o f I E (according to questions) ⇒ 10 mA = 90 100 I E Or I E = 10 × 10 9 ≈ 11 mA I B = I E - I C = 11 mA - 10 mA = 1 mA
