A p-n junction is designed to withstand currents upto a maximum of 10 mA. A resistance of \mathrm{200 \Omega } is connected in series with it. When forward biased, the diode has a potential drop of 0.5 V, which is independent of current. Find the maximum voltage of the battery that can be applied to safely forward bias the diode.

Option: 1

1.5 V


Option: 2

2.5 V


Option: 3

3.5 V


Option: 4

4.5 V

The maximum voltage of the battery whose emf, when
applied, can safely forward bias the diode is

\mathrm{\begin{aligned} & 0.5 \mathrm{~V}+10 \mathrm{~mA} \times 200 \Omega=2.5 \\ &\mathrm{~V}\end{aligned}}
