AIIMS 2018 Physics Diode Circuits MCQ Question
A silicon diode has a threshold voltage of 0.7 V. If an input voltage given by 2 sin (πt) is supplied to a half wave rectifier circuit using this diode, the rectified output has a peak value of
2 V
1.4 V
1.3 V
0.7 V
Correct Answer
Detailed Explanation
The peak value of the rectified output voltage is calculated by subtracting the forward voltage drop of the diode (0.7 V) from the peak input voltage (2 V), resulting in a rectified output of 1.3 V. This value represents the maximum voltage available after rectification, making option C the correct choice. Other options are not applicable as they do not provide relevant values or calculations related to the rectified output voltage. Understanding the significance of the diode's forward voltage drop is crucial in analyzing rectifier circuits and their efficiency.
