Un moteur électrique conçu pour 50Hz pourra fonctionner avec du 60Hz mais tournera plus vite, et un moteur 60Hz tournera moins vite s'il est alimenté en 50Hz. Enfin, les appareil utilisant des chargeurs (téléphone mobile, ordinateur portable)
Une fréquence plus élevée conduirait à des coûts de transport supérieurs et une fréquence trop faible risquerait d'être visible sur les ampoules, que l'œil humain verrait scintiller. POURQUOI 50 Hz ? Les centrales doivent à tout instant produire la quantité d'électricité nécessaire à l'alimentation de la consommation.
