Question
A 2V battery is connected across AB as shown in the figure. The value of the current supplied by the battery when in one case battery′s positive terminal is connected to A and in other case when positive terminal of battery is connected to B will respectively be :


Options
A.0.4 A and 0.2 A
B.0.2 A and 0.4 A
C.0.1 A and 0.2 A
D.0.2 A and 0.1 A
Solution
When positive terminal connected to A then D1 is forward biased
I =
= 0.4A
When positive terminal connected to B then D2 is forward biased
I =
= 0.2A
Option (1)
I =
When positive terminal connected to B then D2 is forward biased
I =
