Question

For the series diode configuration of the given figure, determine \(V_D\) and \(I_D\).

• A. \(0.4 \text{ V and } 0 \text{ A}\)
• B. \(0.7 \text{ V and } 0.85 \text{ A}\)
• C. \(-0.7 \text{ V and } 0.23 \text{ A}\)
• D. \(0 \text{ V and } 0.31 \text{ A}\)

Hint:

For silicon diodes: \[ V_{\gamma}\approx0.7V \] If the applied forward voltage is less than \(0.7V\), the diode remains OFF and: \[ I_D=0 \] In OFF condition, the diode behaves like an open circuit and the entire supply voltage appears across the diode itself.

Answer 1

The Correct Option is A
