Q 26
Draw the circuit diagram to study the characteristics of npn
transistor in common emiiter configuration
Sketch typical i) input characteristics ii) output characteristics
for such configuration
explain how the current gain of transistor is calculated from
output characteristics
OR
Input signal A and B are applied to the input terminal of the
dotted box set up shown here Let Y be
the final output signal from the box
draw the wave form of signal labelled
â€‹C1 and C2 within the
box, giving (in brief) the reason for the getting these wave forms
Hence draw the wave form of the final output signal Y Give reason
for your choice What can we state ( in words) as the related
between final output signal Y and the input signal A and B?

Pintu B. · Accepted Answer

Dear Student, Circuit diagram of common emitter configuration :

Input characteristic curve :

Output characteristic curve :

The current gain β can be obtained by drawing a vertical line as shown at any given VCE Then, we should find the change in collector current ∆IC corresponding to two given valuesof ∆IB Thus,β=∆IC∆IBVCE=constant Regards
