Circuit de l'éclairage d'un scooter Les scooters possèdent des feux de croisement allumés
de jour comme de nuit. C'est pourquoi ils disposent d'un
témoin lumineux de 1,5 V qui s'éteint lors d'une défail-
lance de l'éclairage.
Le phare du scooter de Malia est grillé. Elle part acheter
une nouvelle lampe, mais hésite entre deux : l'une ayant
une tension nominale de 6 V, l'autre de 12 V.
1. Le phare et le témoin lumineux sont-ils branchés en
série ou en dérivation ?
2. À quelles conditions les deux lampes (témoin et phare)
brillent-elles normalement ?
3. Sachant que la batterie du scooter de Malia délivre
une tension de 12 V, quelle lampe doit-elle utiliser ?
Merci d’avance
