Answer:
42-(2) because as key locked then resistance increases suddenly so current will decreases (I=v/r)
43-(4) only 1 amp. can passe through ammeter (capablity),left 9 amp pass through shunt
current is inversely proportional to resistance
for 9 times more current =1/9 times of resistance
so resistance of dd shunt is 0.81/9=0.09
44- (3) total resistance= 1.5
so ,current=6.0/1.5=4amp
45-(3) capablity of voltmeter= 1v(1ohm)
resistance directly proportional to voltage
do,for 99 more voltage=99 more ohms..
