Jump starting a car

Page history last edited by Joe Redish 5 years, 9 months ago



At the right is shown the start of a basic diagram of a car's electrical system. The starter motor is shown, with a switch that turns on when you turn the key all the way.


  1. Make a copy of the diagram and draw in the radio and the headlights. Explain your reasoning for connecting them as you did.
  2. When you jump start a car, you connect another car's battery terminals + to + and - to -. Explain why, using the ideas in this course, and include what would happen if you connected the terminals + to - and - to + .
