Digital Electronics And Logic Gates

Step 1: Recall the Truth Table for the AND Gate

An AND gate gives an output of 1 only if both inputs are 1. Otherwise, the output is 0.

Step 2: Compare the Outputs

The output of the given logic gate matches the truth table of an AND gate:

$ $

Step 3: Conclusion

The output of the given logic gate is the same as that of an AND gate.

In option (1)

To Balance Bridge

$ $

The diode can conduct and have resistance R_D=10Ω because diode have dynamic resistance. In that case bridge will be balanced.
