Question

Before the saturation state of a diode at the plate voltages of 400 V and 200 V respectively the currents are i₁ and i₂ respectively. The ratio i₁/i₂ will be.

• A. $\sqrt{2}/4$
• B. $2\sqrt{2}$
• C. 2
• D. ½

Answer 1

Answer: (C)

2

Answer 2

Before saturation region, linear region comes. In linear region $i_{p} \propto V_{p}$

$\Rightarrow \frac{i_{1}}{i_{2}} = \frac{V_{p_{1}}}{V_{p_{2}}} = \frac{400}{200} = \frac{2}{1}$.
