Malay sa relay na yan. =( A BIG NO NO. (part 3)

Anong mangyayari pag naconnect ang isang AC relay sa DC?

Ang isang AC relay coil has both inductance and resistance limiting the current.
Generally, ang AC relay ay nakadesign nang may mas mataas ng current kesa sa DC
(kasi mas less efficient ang AC). Pag naikabit ito sa DC at hindi sa AC, magkakaroon ng mas
mataas na current pa rin. The relay would operate properly (for a while) but would eventually
fail due to the coil overheating. Depending on ambient temperature and the specific relay,
failure could occur in minutes, or might take years.
