Concord Consortium
Concord Consortium Where Does the Energy of a Spark Come From?
Activity 3 investigates Why is lightning so much bigger that a spark from the Van de Graff generator? In Activity 3 of this module, students investigate factors that affect the amount of potential energy that is stored.
