Ni lo e. Possiive lam. AC atang pawhin hemi lam hian possitive a pe chhuak e.. Diode hi a hmanna a zirin a cathode (negative) hi posstive ni sa pek luhna tur anih chuan a Anode (possitive) anga sawi a ni ve tho bawk. Amah tawp bik sawi fiah dawn chuan a a tlang var lam hi positive tih a ni bik.. AC (posstive/negative) la insiam hrang ve lo a tanga negative/possitive siam anih hian a chiang ber mai. A tlang var lam hian possitive in a siam chuak.
A volt hi 250v a niha 12v aia a san loh a ngai. Chuan, 9v hi regulara a lu chuan a sound pawh a awm phakin ka hria. A volt hi 12v aia sang leh 2A aia a sanin a chhe duh.
