Alimentare mini aparat masaj


Recommended Posts

Buna ziuaPrecizez de la bun inceput am cunostinte mediocre in electronica.Am un mic aparat pentru masaj, care este alimentat exclusiv de la baterii - 2 x 1,5VEste vorba de baterii cilindrice din cele mai mari (groase).As vrea sa-l alimentez cu un alimentator.Am un alimentator, dar tensiunea de iesire este de 12V cu 200mA.Ce trebuie sa pun in serie (pe unul dintre fire - probabil o rezistenta) - ce valoare ?Cum arata o astefel ce rezistenta - am ceva prin casa - de 1K, 10K - tip pastila de culoare cafeniu- maronie.Amperajul are o valoare buna ?Multumesc.
