प्रश्न
In a npn transistor circuit, the collector current is 10 mA. If 95 per cent of the electrons emitted reach the collector, which of the following statements are true?
- The emitter current will be 8 mA.
- The emitter current will be 10.53 mA.
- The base current will be 0.53 mA.
- The base current will be 2 mA.
विकल्प
a and c
a, c and d
b and c
b, c and d
उत्तर
b and c
Explanation:
According to the problem, the collector current is 95% of electrons reaching the collector after emission. And collector current, IC = 10 mA
IE = Emitter current
Also, `I_C = 95/100 I_E`
⇒ `I_E = (10 xx 100)/95` = 10.53 mA
Also, `I_B = I_E - I_C` = 10.53 – 10 = 0.53 mA
