Question:

Find the output voltage in the given circuit.
output voltage in the given circuit
 

Show Hint

For a diode to conduct, it must be forward-biased. In a reverse-biased condition, the diode does not conduct, and the output voltage will depend on the circuit configuration.

The Correct Option is B

Solution and Explanation

In the given circuit, we have two diodes \( D_1 \) and \( D_2 \). The voltage across the diodes and the resistor is affected by the direction in which the diodes are connected and their characteristics. 
- \( D_1 \) is forward-biased because its anode is connected to +5V, and the cathode is connected to the node where \( V_o \) is measured.
- \( D_2 \) is reverse-biased because its anode is connected to the node \( V_o \), and its cathode is connected to ground.
Since \( D_2 \) is reverse-biased, it will not conduct, and \( D_1 \) will conduct. Therefore, the output voltage \( V_o \) will be zero because the voltage drop across the conducting diode \( D_1 \) is almost zero in a forward-biased condition.
Thus, the output voltage is zero.
Therefore, the correct answer is (2) Zero.
