Question

Why wood is a good insulator

Answer 1

Wood works well as an insulator because of all the empty space that it contains. Insulators contain heat and other forms of energy rather than transferring them to another object. Conductors, on the other hand, transfer energy easily; many metals are among the very best substances for energy transfer.

Answer 2

As wood's electron are very compact and very
attached to each other and thier force of attraction are very strong and electricity needs free electrons to flow but its contrasting in wood so its a good insulator..
