Question
The forbidden energy band gap in conductors, semiconductors and insulators are `"E"_("g"_1), "E"_("g"_2) "and" "E"_("g"_3)` respectively. The relation among them is ____________.
Options
`"E"_("g"_1) = "E"_("g"_2) = "E"_("g"_3)`
`"E"_("g"_1) < "E"_("g"_2) < "E"_("g"_3)`
`"E"_("g"_1) > "E"_("g"_2) > "E"_("g"_3)`
`"E"_("g"_1) < "E"_("g"_2) > "E"_("g"_3)`

Solution
The forbidden energy band gap in conductors, semiconductors and insulators are `"E"_("g"_1), "E"_("g"_2) "and" "E"_("g"_3)` respectively. The relation among them is `"E"_("g"_1) < "E"_("g"_2) < "E"_("g"_3)`
Explanation:
The prohibited energy gap in insulators is quite big, in semiconductors it is small, and in conductors it is nil.
