1.1 Electricity is the transfer of energy through the motion of charge-carrying electrons.
1.2 An electron.
1.3 The conductor with the highest resistance would get hotter.
1.4 The conductor would get cooler if you shortened its length.
1.5 A conductor with a larger cross-sectional diameter has lower electrical resistance.
1.6 The purpose of the insulation around a conductor is to prevent electrical shock and to prevent faults to ground and other conductors.
1.7 If the resistance of a conductor is too high or the current flowing through the conductor is too high, then the insulation will start to break down. If it gets hot enough it can melt the insulation.
1.8 When an electron is pulled ...
