Q1. The forbidden energy band gaps in conductors, semiconductors and insulators are \(EG_{1},\) \(EG_{2}\) and \(EG_{3}\) respectively. The relation among them is:

\(EG_{1}=EG_{2}=EG_{3}\)
\(EG_{1}<EG_{2}<EG_{3}\)
\(EG_{1}>EG_{2}>EG_{3}\)
\(EG_{1}<EG_{2}>EG_{3}\)

Q2. Under what conditions will diode \(D_1\) conduct?

\(V_A>V_B+V_0\)
\(V_A<V_B+V_0\)
\(V_A>V_B-V_0\)
\(V_A<V_B-V_0\)
