In a n–p–n transistor circuit, the collector current is 10 mA. If 90% of the electrons emitted reach the collector then
(1) Emitter current will be 9 mA and base current will be 1 mA
(2) Emitter current will be 11 mA and base current will be 1 mA
(3) Emitter current will be 11 mA and base current will be –1 mA
(4) Emitter current will be 9 mA and base current 1 mA
