Because the atoms are tight together unlike in conductable metals which have their atoms freely moving.
No! Any object made of wood donot allow electric current to pass through it.
Materials that do not allow electric currents to pass are called insulators.
coz wood is an insulator, where there's no free electrons n thus current pass through the wood :)
An insulator will not allow much current to pass. There is a large quantity of insulating materials. There are no perfect insulators or conductors.
a electrical insulator is a kind of material that does not allow electricity to pass through it.

objects which can hold air in them behave as insulaters for example fur,wool,dust etc
Insulator. Wood does not allow electricity to pass through it nor does it conduct electricity.

An insulator. (plastic, glass, porcelain, wood, rubber...)
Incorrect. Any material that allow electric current to pass through it is a conductor.
because they does not allow any light to pass through them
NO!!! The whole point of an insulator is to stop electric flow.
That would be an insulator. A few examples include paper, glass or Teflon.
