In a common base configuration, emitter current is obtained as 1 mA and collector current
00:19
is obtained as 0.95 mA.
00:22
The value of base current is a, 1.95 mA, b, 0.95 mA, c, 1.05 mA, d, 0.05 mA is emitter current
00:44
is the sum of collector current and base current.
00:52
So we have to find base current.
00:54
So this equation will become is base current will be equal to emitter current minus collector
01:03
current.
01:04
Because here collector current is positive, when we will take this on the other side of
01:09
equal, then it will be negative.
01:14
So base current will be obtained as emitter current is obtained as 1 mA minus collector
01:26
current is obtained as 0.95 mA.
01:33
So base current will be obtained as 1 minus 0.95 mA, then it will be 0.05 mA.
01:48
So the correct option will be D 0.05 mA.
01:55
which is now the correct one.
01:56
So the reinforcement can be taken on the other side of the double-æ”»esh.
