Comment appelle-t-on l'énergie emmagasinée dans un champ électromagnétique ou électrostatique?

  1. AL'énergie potentielle
  2. BL'énergie cinétique
  3. CLes ampères-joules
  4. DLes joules-coulombs

Correct answer: A — L'énergie potentielle. Question tirée de la banque officielle d'ISDE.

Why

Potential energy is the correct term because it describes energy held in readiness within a field, much like a stretched spring or a raised weight, waiting to be released. The full explanation — and one for every question — is in Pro.
