The given circuit has two ideal diodes connected as show in the figure. The current flowing through the resistance `R_(1)` will be

Options

A. `1.43 A`
B. `3.13 A`
C. `2.5 A`
D. `10.0 A`

Answer

C

Explanation

Current will not flow through `D_(1)` as it is reverse biased. Current will flow through cell, `R_(1),D_(2)` and `R_(3)`.
`:. i=10/(2+2)=2.5 A`
