Question
In a positive clipper, the diode conducts whenNone of theseVin<VrefVin>VrefVin=Vref
Solution
In a positive clipper, the diode conducts when Vin > Vref. This is because in a positive clipper, the positive half cycles of the input signal are clipped off or modified. When the input voltage (Vin) is greater than the reference voltage (Vref), the diode becomes forward-biased and starts conducting.
