ESE 2021 Technical Quiz || Power Semiconductor Diodes

Consider ideal diode in the given circuit. The input waveform is given below. What will be the output waveform?

In the circuit shown below, the which of the following data are correct,

(i) i₁ = 0

(ii) i₁ = 2 mA

(iii) i₂ = 2 mA

(iv) i₂ = 4 mA

Consider the following statements regarding Zener diode.

1. The zener voltage V_Z doesn’t vary with temperature.

2. The zener diode degrades the input signal due to its transition capacitance.

3. Regulation of the zener diode is adversely affected at the knee current Iz(min) due to limited power dissipation capacity.

4. In simple zener diode regulated circuit, amplification isn’t possible.

Which of these statements are correct?
