Dry wood which has dead cells and fibrous materials does not have free electrons to conduct electricity. Am I right?

Metal atoms have loose electrons in their outermost shells, which are called valence electrons. The free electrons conduct electricity by moving through a material and carrying an electric charge.

Human body: Ions in a liquid or aqueous solution conduct electricity. The human body conducts electricity because it contains ions that can conduct electricity.

Electric current can cause death by disrupting the heartbeat, disfiguring burns to the skin, as well as damage to internal organs, muscles, veins, and arteries.
