CBSEENPH12038835

The given circuit diagram shows a transistor configuration along with its output characteristics. Identify
(i) the type of transistor used and
(ii) the transistor configuration employed.

Using the curve, find the gain at VCE = 3 V 



Solution

(i) The transistor used is n-p-n transistor. 

(ii) The transistor configuration employed is common emitter (CE) configuration.

Numerical:

Current amplification factor is given by, 

                           βac = ICIB at vCEβac = ICIB at vCE = 3V

From the characteristic curve, 

                 βac = (9.5-2.5)mA(60-10)μA 

                          = 7.0 × 10-350-10-6 = 140.
