Analog circuits miscellaneous

  1. What are the states of the three ideal diodes of the circuit shown in figure given below?

    1. D1 ON, D2 OFF, D3 OFF
    2. D1 OFF, D2 ON, D3 OFF
    3. D1 ON, D2 OFF, D3 ON
    4. D1 OFF, D2 ON, D3 ON
Correct Option: A

Analysing the circuit we can see that D1 and D2 are in forward bias and D3 is in reverse bias. But no current flows through D2 because current gets shortest path through D1.
