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