JEE Main 2 April 2026, Shift 1, Physics Q37

Question 37 of 75 in this shift, Physics question 12 of 25, Section A.

For the given circuit (shown in part (A)) the time dependent input voltage vin(t)v_{in}(t) and corresponding output vo(t)v_o(t) are shown in part (B) and part (C), respectively. Identify the components that are used in the circuit between points X and Y.

The figure, in words

Part (A): source v_in across a branch containing an ideal diode in series with a Zener diode (V_Z = 5 V) that is in parallel with a load between points X and Y (output v_o). Part (B): sinusoidal input v_in(t) with amplitude 20 V and -20 V, t in min with marks 1 and 2. Part (C): output v_o(t) clipped to a flat-topped waveform at +5 V and -5 V.
