Question

The power gain for CB amplifier is 800 &
voltage amplification factor is 840. Find the
collector current when the base current is
12 mA.

use relation ,
[ power gain = voltage gain × current gain(ß)]​

Answer 1

Answer:

First find current gain

$840 = 800 \times \beta \\ \\ \beta = \frac{840}{800} = \frac{21}{20}$

So

$i_{c} = \beta i_{b} = 12 \times \frac{21}{20} = 12.6 \: amp$
