question 1 This is slowing the flow of electrons (the current) and where some of the electrons' energy gets converted into heat.


question 2 These stop the electricity from flowing (think rubber and glass).


question 3 This is a flow of electrons (such as the flow of electrons in a wire to light up a lamp).


question 4These allow electricity to flow easily through them (think copper and aluminum).


1. Electric Current
