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

2. Resistance

3. Conductor

4. Insulator
