Comment appelle-t-on l'énergie emmagasinée dans un champ électromagnétique ou électrostatique?
- AL'énergie potentielle
- BL'énergie cinétique
- CLes ampères-joules
- 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.
