Question

In a n-p-n 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? (A) The emitter current will be 8 mA (B) The emitter current will be 10.53 mA (C) The base current will be 0.53 mA (D) The base current will be 2 mA

Here, Ic=10 mA , Ic=(95/100) Ie ∴ 10 mA =(95/100) I e or I e =10 × (100/95)=10.53 mA

Q. In a $n - p - n$ transistor circuit, the collector current is $10 m A$ . 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

Here, $I_{c} = 10 m A, I_{c} = \frac{95}{100} I_{e}$
$∴ 10 m A = \frac{95}{100} I_{e}$
or $I_{e} = 10 \times \frac{100}{95} = 10.53 m A$
