Here in this question we have to draw the energy bands for insulators, semiconductor and conductor.
00:10
Let's first discuss about insulator.
00:12
So basically, insular later is that material in which current does not flow easily.
00:18
Examples of that material are like wood, paper, plastic, oil, mic, etc.
00:27
The reason for this insulation is a wide gap between the, valence point and a conductant band let's say this is a vb let's say this is a valence band and here it is the conductance band that is cb so there is a large distance so electrons is it is very difficult for electron to jump from valence band to conducting band this is forbidden zone band or gap that's why insulators are bad conductor of electricity now next we are going to this about the conductors.
01:02
Conductors are material in which current flows easily.
01:06
For example, silver, copper, aluminium, etc...
