JEE Main 28 June 2022, Shift 2, Physics Q49

Question 49 of 90 in this shift, Physics question 19 of 30, Section A.

In the given circuit the input voltage VinV_{in} is shown in figure. The cut-in voltage of p-n junction diode (D1D_1 or D2D_2) is 0.6 V. Which of the following output voltage (VoV_o) waveform across the diode is correct ?

The figure, in words

Left: graph of V_in (V) vs t (sec.), a sine wave with dashed horizontal levels marked 0.6 V above and below the axis. Right: circuit with the source V_in (~) in series with a resistor R ohm, and diodes D1 and D2 connected in parallel across the output v_o, pointing in opposite directions (D1 down, D2 up); v_o is marked with arrows at the output terminals.
  1. (1)[figure: graph of V_o vs t, one full sine cycle (positive half then negative half), dashed vertical lines at the end of each half-cycle]
  2. (2)[figure: graph of V_o vs t, positive half sine only, then flat along the t axis (zero)]
  3. (3)[figure: graph of V_o vs t, flat-topped (clipped) pulses above the t axis, top level marked 0.6 V, returning to zero at each dashed line]
  4. (4)[figure: graph of V_o vs t, positive half-cycle clipped flat at +0.6 V and negative half-cycle clipped flat at -0.6 V, both levels marked 0.6 V]Official answer

Question text from the official JEE Main paper published by NTA; answer from the final answer key. Chapter, topic and idea tags, difficulty and skill are Lumi’s. This question needs a figure we do not reproduce; it is described in words above. Lumi analyses 108 of the 174 JEE Main shifts held from 2017 to 2026.
