Electrons have less mass than a neutron.
Answer:
Covering electrical wires in plastic guarantees that the electrons flowing through the wires will not flow through your body when the wire is touched.
Explanation:
"The purpose of insulation covering the metal part of an electrical wire is to prevent accidental contact with other conductors of electricity, which might result in an unintentional electric current through those other conductors."
