AIIMS 2018 Physics Rectifiers MCQ Question
In a full wave rectifier in which input voltage is represented by V = Vₘ sin ωt, then peak inversion voltage of non conducting diode will be:
−Vₘ
Vₘ/2
2Vₘ
0
Correct Answer
Detailed Explanation
In a full wave rectifier, the peak inversion voltage of the non-conducting diode occurs when the input voltage reaches its maximum negative value, which is equal to the negative peak of the input AC signal, represented as −Vₘ. This means that when the diode is reverse-biased, it experiences a peak voltage of −Vₘ, leading to option C being correct. Option A is incorrect because it only states the negative peak without considering the rectification process, while options B and D do not accurately reflect the peak inversion voltage experienced by the diode during operation.
