Two ideal junction diodes `D_(1),D_(2)` are connected as shown in the figure. A `3V` battery is connected between `A` and `B`. The current supplied by the battery if its positive terminal is connected to `A` is
.

Options

A. `0.1 A`
B. `0.3 A`
C. `0.9 A`
D. `90 A`

Answer

B

Explanation

If positive terminal is connected to `A,D_(1)` in forward bias and `D_(2)` is in reverse bias. So `20 W` is ineffective.
`:. i=(V)/(R)=(3)/(10)=0.3A`.
