Electric Circuits Describe what is an electric current. What is a simple circuit? A circuit is a route from which electricity can flow through from the negative side of the battery , electrons flow through the conductive side, through the wire in the bulb causing the bulb to light Describe what is current. A current is electricity going through a circuit Explain what is voltage. A measure of energy available to move the push that makes the electrons move Series and Parallel Circuits Use the link Circuits Create a series circuit and look at how bright the bulbs are. Remove one of the bulbs and see what happens to the other light. Create a parallel circuit and look at how bright the bulbs are. Remove one of the bulbs and see what happens to the other light. In which circuit are the light bulbs brighter? In Christmas tree lights how would you want the bulbs wired? Series or Parallel? Explain your choice.
