Answers
A1 : Because the air is a very poor conductor. Electricity is basically electrons on the move. In air, the atoms are far from each other. Hence, the poor conductivity.
A2 : The melting point of a fuse should be lower than the nonconductor that is rapped around the wire. Rubber or plastic, in most cases
