Question

. i) With thc help of a circuit diagram, explain how a transistor can be used as

an amplificr in common-cmitter configuration. t6]

ii) Why CE, configuration is preferrcd ovsr othcr configuration for transistor

amplificr?

iii) In a transistor, 50 pA basc current is rcquired to change the collector current

by I rnA. Calculatc current gain B.
​

Answer 1

Answer:

it is so easy but it only can be done on copy

Answer 2

Answer:

because ce configuration has high current gain and high voltage gain and the ratio of input impedance to output impedance is low
