question

prove that in a common-emitter amplifier, the output and input differ in phase by . in a transistor, the change of base current by 30 produces change of 0·02 v in the base-emitter voltage and a change of 4 ma in the collector current. calculate the current amplification factor and the load resistance used, if the voltage gain of the amplifier is 400.
