MOP Connection 1 Insulators are different than conductors in that insulators 2 3 http www physicsclassroom com Class estatics u811e html Static Electricity preface to sublevels 5 7 a do not contain electrons or protons c have a weaker affinity for electrons 7 Materials through which electrons can move readily are classified as a conductors b insulators c semi conductors The diagram at the right shows a metal sphere attached to the top of an insulating stand The metal sphere contains an excess of electrons and is thus charged A student holds various objects in her hand and touches the object to the sphere Which of the following objects below would allow charge to flow through it when the student touches the object to the sphere a a plastic straw c a steel house key e a strip of aluminum 4 1 1 5 TRUE or FALSE b do not contain any charge d do not allow charge to freely move foil Explain your answer b a piece of paper d a metal paper clip Consider these two spheres They have both been charged In one case the charge is isolated in three distinct locations in the other case the excess charge is even distributed about the surface of the sphere Which one of these spheres is made of an insulating material and which is made of a conducting material Label which is which and support your answer with an explanation Conductors cannot be charged by frictional rubbing 6 A balloon is charged by rubbing it with animal fur It is then pressed against a wooden cabinet The balloon and cabinet attract seeming to defy the force of gravity This attraction is best explained by a induction charging of the wood b frictional charging of the wood c polarization of wood molecules d polarization of balloon molecules The above effect in question 6 is most often noticed of a conductors b insulators c charged objects 1 9
