Because its doesn't allow the current. So its an insulator.

It does not allow the movement of electron into it "that is why insulator".

Why we measure electricity in voltage ? not in ampere.

Please give clear description for the answer.

Because insulator has high resistance so current is zero.

Conductor- Allows the flow of Electron.
Insulator - Opposes the flow of electron.
Semiconductor - Sometimes allows or opposes the flow of electron.
Insulator - Opposes the flow of electron.
Semiconductor - Sometimes allows or opposes the flow of electron.

For insulator the depletion region width is hagh between the valance band and conduction band. so there is no flow of free electrons.

Insulator have high resistance. So current is zero.

Consider current as peoples getting down from a bus.
Conductor - bus having 2 doors
Semiconductor- bus having only one door
Insulator- bus having no doors :)
