Correct the sentence: The aim of using coupling in multistage transistor amplifiers is to transfer DC output of one stage to the input of the next .stage and to isolate the d.c. conditions of one stage from the next stage

Q4:Choose the correct items of the following statements: 1-The tail current of a diff amp is a-Half of either collector current. b-Equal to cither collector current. c-Equal to difference in base currents. d-Equal to emitter current. 2-The voltage gain of a diff amp with an unloaded differential output is equal to Rc divided by a-r.. b-r/2. c-2r. d-RE 3-A-commmon -mode signal is applied to a-The nan inverting input. b-The inverting input. c-Both inputs. d-The top of tail resistance. 4-The common -mode rejection ratio is a- Very low. b- Often expressed in decibels. c- Equal to the voltage gain. d- Equal to the common- mode voltage gain. 5- The input offset current is usually a- Less than the input bias current. b- Equal to zero. c- Less than the input offset voltage. d- Unimportant when a base resistance is used. 6-With both bases grounded the only offset that produces an crror is the a- Input offset current. b- Input bias current. c- Input offset voltage. d- B. 7-A compensating…
