Quick explanation

Explain simple experiments that demonstrate how electrostatic charges are generated through friction and how they can be detected

  • This point belongs to Electric charge, especially Electric charge outcomes.
  • You need to be able to explain simple experiments that demonstrate how electrostatic charges are generated through friction and how they can be detected.
  • The key ideas to know are Describe and Investigate.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
