A conductor is a material that has one or a few electrons in the outer shell of its atoms. These electrons are easily knocked loose, or are already moving about in the material. When a voltage is applied to a conductor, these electrons are repelled by the negative polarity and attracted by the positive polarity. Their movement is called "current".
a conductor is a material that transports electrons and electricity can pass through it, metals are good conductors.
a insulator is something that is a barrier to electrons and can not pass electricity, rubber is a good insulator.
