high voltage gain is obtained from CB configuration only.
because the input impedance is low and out impedance is
high in CB configuration. so we get maximum voltage gain in
CB. whereas for CE the input impedance is moderate and
output impedance is moderate. so we get maximum power gain
from CE. and CC voltage gain is approximately one. so this
will give maximum current gain. CC is used for impedance
matching. CC is also known as emitter follower. because of
its unity gain.
cb will have max voltate gain.
ce will have max power gain.
cc will have max current gain.

Answer / dhaval
we can get only voltage amplification from CB configuration
.And we can get voltage and current amplification from CE
configuration. so we get high voltage from both of CE & CB
configuration.

no doubt the maximum voltage gain will be obtained from CB
configuration only. for the answer 6: we dont connect any
resistors on either side of input and output. by its
connection we get input and output resistances. we know the
doping concentrations of emitter, base and collector.
depending upon the configuration we get input and output
impedences. nothing else.

Answer / daxesh
Agree with ans 5.
and for above query that R will be considered same in both configuration. Then ans 5 is correct.

Answer / tinku.kne@gmail.com
we can get highest voltage from cb configuration
coz, transistor iss a current contld device so, we 've max
current gain from ce mode and

I have a book in which same data is given... and that data is misprinted and is not reliable.
Better you refer a book of another writer.

Answer / reema
i am agree with answer 5
highest voltage gain can be obtained by CB
because its input impedence is low and output impedence is
high so it can give highest voltage gain
