  1. 0.66 A
  2. 0.05 A
  3. zero
  4. 0.04 A

A
0.66 A
B
0.05 A
C
zero
D
0.04 A
Solution
Verified by Toppr

The circuit is as shown as image 1.
As the lower diode attached to 100 Ω resistance is in reversed biased so, it is non-conducting.
Now, the circuit can be redrawn as image 2.
Current through the circuit, I=VR=10250=0.04 A
